FOLIC ACID

At Cadabams Diagnostics, the Folic Acid Test is used to diagnose folic acid or vitamin B9 deficiency in an individual’s body. This test is critical because folic acid is important in many of the body’s functions and having an informed health status could improve one’s life. This page tells you what the Folic Acid Test is about, why it is important, how to prepare for it, and how to interpret the results.

Folic Acid (or Vitamin B9), a dietary component, is critical for the body to function properly. Unlike other nutrients, it is not produced in the body. The Folic Acid Test determines whether there is enough of this nutrient in the body.

Why do we need folic acid?

• Cell Partitioning and Growth: Folic acid plays an integral role in the stern, division and group internal processes within an organism. That makes it important during the development stages which includes hypergrowth periods like infancy, adolescence and pregnancy.
• Cellular Maintenance, Repair and DNA Synthesis: Folic acid is pivotal for the forming, repairing and functioning for any organism’s DNA and RNA strands.
• Red Blood Cell Formation: Folic acid together with vitmain B12 is important in the formation of new healthy red blood cells responsible in carrying oxygen throughout your system. It’s deficient on some nutrient can lead to megaloblastic anemia – a type of anemia that can further lead on health complications.
• Regulating Nervous System: Helps in the maintenance of nerves within the body.
• Overall Health: Having adequate levels of folic acid is associated with lower chances of developing specific health issues. Knowing why is folic acid important helps in realizing its role.
• Pregnancy and Fetal Growth: Women need folic acid before and during pregnancy for many reasons. Having optimal levels of folic acid minimizes the chances of NTDs spina bifida and anencephaly occurring in the fetus. This is one of the many reasons why folic acid benefits for women are advertised heavily.

The Folic Acid Test measures the concentration of folate (active form of folic acid) in the blood serum. This measurement reflects recent intake of folic acid, as well as to some degree, the body’s reserves.

The blood sample that you bring to your Cadabams Diagnostics laboratory is centrifuged to obtain the serum portion. After that, a battery of tests is performed to determine the amount of folate present in the serum. Results are, as a rule, given in ng/mL or nmol/L.

Doctors, at times, might resort to conducting an RBC (Red Blood Cell) folate test, although the serum Folic Acid Test is a routinely used test. The RBC folate test has a better assessment of folate status as it captures a longer duration (approx 120 days) as it measures the age of the RBCs. It can be more precise in determining nutrient stores within the tissues, especially when serum levels are highly variable due to recent dietary changes, as is often the case with fluid intake. Your doctor will decide which test is suitable in your case.

Folic Acid Test may be prescribed by a practitioner in Cadabams Diagnostics for the following purposes:

• Deficiency Diagnosis: If you exhibit any signs of folic acid deficiency. These include experienced unrelenting tiredness, breathing difficulties, pale skin colour, weakness, skin sense of flaw looking or feeling obligative, reduced muscle power, overly active temper, aggravation, emit mouth or oral cavity sores, tick in the sun swollen tongue (talk glossitis), as well as hair, skin, or fingernail pigmentation shift. In addition to these, there may be more neurological signs like tingling or numb feeling in hands and feet though this sign is mostly linked to deficiency of vitamin B12 and does often test with folic acid.
• Nutritional Assessment: As part of the more comprehensive of a nutritional evaluation for select individuals with dietary concerns and a high probability of nutritional deficiency, it targets individuals with:
• Malnourished or with insufficient food intake.
• Nutrient Absorptive disorders such as celiac disease or Crohn’s disease cause nutrient deficiency through improper absorption.
• A history of long-term alcohol dependency. Alcohol has denoted interference with folate absorption and its metabolism.
• Prenatal Screening: Folate insufficiency can greatly impact fetal development making it more essential for women who are pregnant, planning on getting pregnant, or already breastfeeding. This reinforces the remarkable womb and folic acid benefits for women.
• Monitoring Supplementation: For the person undergoing treatment for a diagnosed folic acid deficiency, the test helps monitor the effectiveness of folic acid supplementation and modify the dose if need be.
• Review of Treatment: If you are currently undergoing treatment with select agents capable of folic acid absorption or metabolism intervention. These include methotrexate for malignancy and autoimmune disorders, some anticonvulsants especially phenytoin and phenobarbital, and sulfasalazine for inflammatory bowel disease are known to interfere.
• Investigating Anaemia: If the complete blood count (CBC)-evaluation along with the first one displays indicators that suggest megaloblastic anaemia is present, a Folic Acid Test, commonly combined with Vitamin B12, will be requested done to assess the cause.

The Folic Acid Test is a common and considered a safe blood test and is done routinely at Cadabams Diagnostics.

Risks

The Folic Acid Test has very few risks and these mostly stem from the blood draw:

• Mild Discomfort or Pain: There's a chance you may experience a mild stinging pain when the needle is inserted.
• Bruising: There may be a little bruise at the site of the puncture. This can be improved by holding pressure after the draw.
• Bleeding: There may be some bleeding, but this is minimal and stops rapidly with some pressure.
• Dizziness or fainting: In some cases, light headedness or fainting can happen during or after the blood draw and informing the phlebotomist beforehand is often helpful.
• Infection: Stated risk may be very low since sterile techniques are always in place.

Limitations

Please note the following factors which may have an impact on interpreting the Folic Acid Test results:

• Recent Intake: Your intake of folate-rich foods and supplements can impact serum folate levels. If a large amount of folate was recently consumed, serum levels may seem elevated, potentially masking a deficiency.
• Medications: Like we discussed before, some medications can modify folic acid metabolism and can alter the results of the test. Make sure that your physician and the laboratory technicians know all the medications and supplements that you take.
• Haemolyzed samples: Where red blood cell lysis (or haemolysis) occurs during specimen collection and processing, this can cause the measurement to be elevated as cells release folate. Cadabams Diagnostics is very careful during sample collection and processing to avoid this.
• Tissue versus serum levels: A normal level of serum folate does not necessarily exclude a partial deficiency at the tissue level, particularly if there are strong symptoms associated with it. In such scenarios a further work up or an RBC folate test may be warranted.
• Combined Deficiencies: The deficiencies of Folic acid and vitamin B12 often accompany each other and can present overlapping symptoms. Excessive consumption of folic acid, particularly from dietary supplements, can sometimes resolve B12-deficiency anaemia while allowing subclinical neurological injury from B12 deficiency to progress. Hence, it is often prudent to evaluate vitamin B12 status as well.

In a Folic Acid Test, the most important parameter to measure is:

• Serum Folic Acid Level: This is defined as the amount of folate (folic acid) in the serum of blood.
• The results are expressed in units such as ng/mL or nmol/L.

At Cadabams Diagnostics, you will have your serum folic acid assessed and evaluated against a reference range. This range is the set of values observed in a population known to be healthy. These reference ranges may differ from laboratory to laboratory because of differences in the testing equipment, reagents, and analytical techniques employed. Hence, they need to be interpreted within the context of the specific reference range given by the laboratory that conducted the test – in this scenario, Cadabams Diagnostics.

Your doctor will explain the value concerning your symptoms, medical history, and other pertinent details.

There are clear reasons why some groups may need to undergo a Folic Acid Test at Cadabams Diagnostics.

• Patients with Deficiency Symptoms: Any person who shows symptoms of folic acid deficiency, including fatigue, weakness, pale skin, breathlessness, mouth ulcers, inflammation of the tongue (glossitis), irritability, and some neurological symptoms like tingling in the limbs or problems with remembering things.
• Women of Reproductive Age:
• Pregnant Women: As part of prenatal care, ensuring adequate folate is critical for healthy fetal development, clearly showcasing the folic acid benefits for women.
• Women Planning to Get Pregnant: To maximize the chances of avoiding neural tube defects, which occur very early in pregnancy, optimal folic acid levels should be in place before conception.
• Women Who are Breastfeeding: Increased nutritional needs during lactation makes monitoring necessary.
• Patients with Gastrointestinal Disorders: Those with diseases that impact the absorption of nutrients, including:
• Celiac disease
• Crohn’s disease
• Inflammatory bowel disease (IBD)
• History of gastric bypass surgery
• People with a History of Chronic Alcohol Consumption: Chronic use of alcohol inhibits the absorption and metabolism of folate.
• Patients Using Certain Medications: Patients using drugs that are known to lower folate levels which include:
• Methotrexate
• Some anticonvulsants: Phenytoin, Carbamazepine, Valproate
• Sulfasalazine
• Trimethoprim, an antibiotic
• Geriatric Patients: Elderly individuals may be more vulnerable due to lower dietary intake, decreased nutrient absorption, and/or chronic diseases.
• People with Anemia: Especially when megaloblastic anemia is considered, a Folic Acid Test is essential towards diagnosing and managing it.
• Those with Insufficient Folate Sourcing Diet: People who do not consume fruits and vegetables, especially green, leafy ones, and fortified grains.

Contact your healthcare professional to discuss taking a Folic Acid Test if any of the examples given apply to you or if you have worries about the state of your folate level.

Conducting a Folic Acid Test in Cadabams Diagnostics Clinic has numerous advantages to your health and overall wellness.

• Preventive Treatment of Deficiency: The screening provides folate deficiency identification before it develops to complicated conditions like megaloblastic anaemia or neurological disorders. Treatment during this stage can restore levels and mitigate symptoms.
• Healthy Development of the Zygotic Structure: For mothers or noting expectant mothers, testing confirms that the mother has enough folate reserve to aid in the foetal neural tube formation. One of the frequently known folic acid benefits for women and cornerstones of prenatal care.
• **Folic acid levels monitoring helps in guiding food choices and supplements for better nutrition. This helps understand what folic acid is used for in nutritional health. ***
• Gives A Broader Overview for Nutritional Health: To get a better understanding of your health, measuring folate levels can be very helpful. This is since multi nutrient imbalances and deficiencies are usually interconnected.
• Understanding Reason Behind Fatigue or Weakness Symptoms: Having low energy or feeling lethargic can make daily activities tough to get through. Moreover, these symptoms can be related to many other underlying issues. Having a Folic Acid Test might bring clarity in identifying whether low folate is the driving factor, so useful treatment can be administered.
• Avoiding Long Term Complications: Untreated chronic deficiency of folic acid can lead to several complications, such as certain types of anaemia (additional details can be found here [Link to Anaemia Information Page]), and eyesight problems depending on the age of the patient. Also, can increase the chances of developing cardiovascular disease, due to increased levels of homocysteine, which folic acid regulates.
• Evaluating Effects of Treatment: If the folate supplementation treatment results are favourable, the use of the folic acid test becomes imperative for patients, as it will aid determining whether the proposed levels and range are indeed achieved.

Using this straightforward blood test, you and your physician can take preventive actions to maintain and improve your well-being by understanding your folic acid levels.

The Folic Acid Test is applicable for diagnoses concerning:

1. Folic Acid Deficiency: This condition is confirmed by the test as it identifies deficiency of folic acid in blood—surely it exists due to peripheral causes like poor dietary intake, malabsorption due to other reasons, higher bodily demand, or certain drugs.
2. Megaloblastic Anaemia: The Folic Acid Test is a critical part of the diagnostic workup for megaloblastic anaemia. This is a type of anaemia that involves the formation of large and immature red blood cells—megaloblasts—in the bone marrow. One of the most important causes of megaloblastic anaemia is folic acid deficiency (the other being lack of vitamin B12).
3. Nutrient Malabsorption Problems: Celiac disease or Crohn's disease are some underlying disorders with abnormal folic acid levels and absorption that result in lack of nutrients to the body.
4. Determination of General Nutritional Status: Apart from other clinical reasons, the test is performed as part of a panel containing other tests which is helpful in evaluating the overall nutritional condition of a patient. In case of dual deficiency of B vitamins, health impact is significant.
5. Hyperhomocysteinemia (Indirectly): As with vitamins B12 and B6, folic acid aids in the metabolism of homocysteine. Even though the Folic Acid Test does not measure homocysteine directly, a low level of folic acid can indeed lead to high homocysteine levels, which is known to increase the risk of cardiovascular disease.

It is vital to appreciate that the Folic Acid Test is only one part of the diagnosis. Your doctor at Cadabams Diagnostics will analyse the results together with your symptoms, medical history, physical examination, and other lab tests if needed to provide a conclusive diagnosis.

Palomar Health is an organization that values precision and professionalism; proper preparation for this test at Cadabams Diagnostics elevates the accuracy of results. Please observe the following instructions.

Instructions:

• Fasting:
• It is common for patients to have 6-8 hour fasting before the Folic Acid Test, and it is mandatory for a patient not to eat or drink anything, except for water, during this time. Please note that these requirements differ from one client to another, so it is essential to clarify details with Cadabams Diagnostics or your referring doctor. Water is mostly acceptable.
• Medications & Supplements:
• Crucially important: It is critical that you communicate to your physician, as well as the laboratory personnel at Cadabams Diagnostics, all medications (including prescription drugs and over-the-counter supplements, as well as multivitamins and particularly B-complex and folic acid vitamins), and herbal medicine being used. Several of them can affect the levels of folic acid. This is especially true considering the folic acid vitamin B9 relationship. It is advisable that you do not suspend any of your medications unless your doctor has directed you to do so.
• Diet:
• Generally following the diet pattern that you have been used to is advisable but avoid eating large portions of folate-rich food prior to your test unless directed to by your physician. Do note that very recent high intake could temporarily elevate serum levels.

Prerequisites:

• Usually, a health professional must first issue a Folic Acid Test Order before you can take the test. The healthcare practitioner will make the decision as to whether this test is necessary based on the patient’s signs, history and examination findings.

Eligibility:

• There are no age restrictions for the Folic Acid Test as it is applicable to everyone, including children and the elderly.
• Anyone with a history of fainting spells when having blood drawn, or with a known bleeding disorder is requested to notify the phlebotomist at Cadabams Diagnostics about the condition prior to sample collection.

Procedure for Taking the Test:

The Folic Acid Test procedure involves a single blood sample:

1. You will be placed in a relaxing position.
2. A trained phlebotomist from Cadabams Diagnostics will find a suitable vein, generally in the inner elbow or on the back of the hand.
3. The area will be scrubbed with an antiseptic wipe.
4. An elastic band (tourniquet) may be placed around your upper arm to make the vein stand out more.
5. A sterile needle will be placed into the vein, and you may feel a pinch.
6. A vial or tube containing sterile blood will be filled with the vacuum created by the special collecting vessel.
7. After the required volume of blood is collected, the needle will be withdrawn and gauze or a cotton ball will be applied on the puncture site with slight pressure to stop bleeding. A bandage will be put over it.
8. The whole process is often completed in a couple of minutes.

Caution Before the Test:

• Discuss any worries or questions regarding the Folic Acid Test with your caretaker or the Cadabams Diagnostics personnel in advance.
• Provide a current list of all medications and relevant medical conditions, including supplements and their dosages.
• As instructed, comply with all fasting protocols specified by Cadabams Diagnostics.
