A serum folate test measures the level of folate (vitamin B9) in your blood. Folate is essential for DNA production, red blood cell formation, and overall cellular function. This test is crucial in diagnosing folate deficiency, which can lead to anemia, fatigue, and other health issues. A deficiency in folate may also be associated with poor nutrition, pregnancy, or conditions like celiac disease. Interpreting serum folate levels helps healthcare providers determine if dietary changes or supplementation is needed to restore optimal health.

The Mean Corpuscular Volume (MCV) blood test measures the average size of red blood cells. A high MCV level means red blood cells are larger than normal, which can indicate vitamin B12 or folate deficiency, or liver disease. A low MCV level suggests smaller red blood cells, which may be caused by iron deficiency or conditions like thalassemia. Abnormal MCV levels can signal underlying health issues and may require further testing to determine the cause. Your doctor can help interpret these results and suggest appropriate treatment based on the findings.

Ferritin is a protein that stores iron in your body, and its levels in the blood reflect your overall iron stores. Low ferritin levels typically indicate iron deficiency, which can lead to anemia, causing fatigue, weakness, and pale skin. High ferritin levels may suggest iron overload conditions like hemochromatosis or chronic inflammation. Both low and high levels can have serious health implications, making it important to monitor ferritin through regular blood tests. If your ferritin levels are abnormal, your doctor may recommend further testing to determine the cause and appropriate treatment.

A Thyroid Function Test (TFT) measures how well your thyroid is working by analyzing hormone levels in your blood. The key components tested are Thyroid-Stimulating Hormone (TSH), Total or Free Thyroxine (T4), and Total or Free Triiodothyronine (T3). TSH regulates thyroid activity, while T3 and T4 are hormones produced by the thyroid that control metabolism. Abnormal results can indicate conditions such as hypothyroidism (low thyroid function) or hyperthyroidism (overactive thyroid). During the test, a simple blood sample is taken, and results guide doctors in diagnosing and managing thyroid disorders.
