Role of Serum Folate in the Body

Serum folate, commonly known as folic acid, is a type of B vitamin which plays the major role in the everyday operation of the body. It contributes to several bodily functions, including the making of red blood cells, DNA synthesis, and cell division.

Red blood cells help to transport oxygen to all the different parts of the body. Adequate serum folate levels help prevent anemia, a condition with a shortage of red blood cells further results in weakness, fatigue, and shortness of breath. Folate deficiency during pregnancy can lead to congenital disabilities such as neural tube defects (NTDs), which affects the brain and spinal cord development of the fetus.

In addition, folate is essential for the growth and development of cells, making it especially important for children and teenagers. It also supports proper brain function and can help minimize the risk of certain chronic diseases, i.e. cardiovascular disease and certain types of cancer.

However, it’s important to note that excessive serum folate levels can also have adverse effects on health. High levels of folate have been linked to an increased risk of colon cancer and can mask vitamin B12 deficiency. Therefore, maintaining optimal serum folate levels is crucial for overall health and well-being.

Normal Range of Serum Folate Levels

Serum folate levels may vary based on age, gender, and medical conditions. The normal range for serum folate levels typically falls between 2.7-17.0 ng/mL in adults, depending on the laboratory conducting the test. However, some laboratories may have slightly different reference ranges.

It is important to note that while the reference range provides a general guide, healthcare professionals may interpret results based on individual patient circumstances. For example, a patient with a medical condition or taking certain medications may have a different optimal range.

Regular serum folate testing is essential to monitor levels and ensure they remain within the normal range for optimal health.

Methods to Measure Serum Folate Levels

There are several methods used to measure serum folate levels. The immunoassay test is the most commonly used method, which detects the folate concentration in the blood. This test is accurate and reliable, making it a preferred choice among healthcare professionals. Another widely used test is the microbiological assay, which measures the growth of certain bacteria in response to varying folate levels. Although this method is less commonly used, it remains an adequate measure of folate levels.

It’s crucial to note that certain factors might affect the accuracy of serum folate testing. These include recent dietary changes, medication use, and pregnancy. For this reason, it’s recommended to avoid any dietary changes or medication use before serum folate testing and inform your healthcare provider of any factors that may affect the accuracy of the test.

The Immunoassay Test

The immunoassay test uses antibodies to detect folate concentration in the blood. The blood sample is mixed with a reagent containing folate labeled with a special dye. If folate is present in the blood, it will bind to the labeled folate, and the resulting complex will be detected by the antibody. The intensity of the signal produced is proportional to the amount of folate present in the blood.

The Microbiological Assay

The microbiological assay measures the growth of certain bacteria in response to varying levels of folate. The blood sample is mixed with a unique culture medium containing a bacteria that requires folate to grow. The model is then incubated under specific conditions, and the growth of the bacteria is measured. If folate is present in the blood, it will support the development of the bacteria. The amount of folate in the blood is determined by comparing the growth of the bacteria to a known standard.

Overall, serum folate testing is essential in determining folate levels in the body. It helps healthcare professionals diagnose folate deficiencies and monitor treatment outcomes. Maintaining healthy serum folate levels is essential to support overall well-being and prevent certain health conditions.
