Serum D-Serine Concentration

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms or conditions linked to abnormal D-serine levels, such as neurological disorders, seizures, or certain metabolic syndromes. It may also be part of research or specialized diagnostic testing for conditions affecting neurotransmission or brain chemistry.

What Does the Result Mean?

D-serine is typically present in small amounts in the blood. Results may be compared to reference ranges provided by your lab, but these can vary by lab. Abnormal results could suggest underlying neurological, metabolic, or other health issues that require further evaluation.

How Is the Test Performed?

A blood sample is drawn from a vein, usually in your arm. The serum portion is separated and analyzed using a specialized laboratory technique to measure D-serine concentration.

What Are Common Causes of Abnormal Results?

While D-serine is mostly involved in brain function, some conditions or medications that affect neurotransmitter balance—such as certain neurological disorders, epilepsy, or metabolic disorders—might influence its levels. However, individual results depend on many factors, including diet, health status, and lab-specific methods.
