SER

Description

"Serine" test checks the level of serine in your blood, an amino acid involved in brain development, nerve function, and metabolism. It’s often recommended for people experiencing fatigue, cognitive changes, or suspected metabolic disorders. Abnormal serine levels may indicate impaired enzyme activity, neurological conditions, or amino acid processing issues. This test helps doctors pinpoint the root of unexplained symptoms and create a tailored care plan, which may involve adjusting protein intake, supportive dietary strategies, or additional neurologic evaluation.

Amino Acid Group, Methylation Group

Test Group Description

Amino Acid Group: Tests in this group analyze amino acid levels in the body, providing valuable insights into protein metabolism and potential genetic or metabolic disorders related to amino acid processing. Methylation Group: Centered on evaluating methylation levels and associated parameters, this group provides insights into methylation processes and their related health implications.

Optimal Range

For All Individuals:

  • Conventional Unit: 6.00–17.20 µmol/dL

  • SI Unit: 60.0–172.0 µmol/L

Normal Range

For All Individuals:

  • Conventional Unit: 4.87–14.52 µmol/dL

  • SI Unit: 48.7–145.2 µmol/L

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • High protein consumption

  • Homocysteinemia (Elevated homocysteine levels)

  • Significant branched-chain amino acids supplementation

  • Vitamin B1 deficiency


Decreased levels may indicate:


  • Celiac disease (Autoimmune reaction to gluten affecting small intestine absorption)

  • Crohn's disease (Inflammatory bowel disease causing digestive tract inflammation)

  • Low protein intake

  • Methylation complications

  • Vitamin B6 deficiency (Inadequate vitamin B6 levels)

  • Ulcerative colitis (Inflammatory bowel disease affecting colon lining)

Key Reasons For Testing

  • Metabolic Assessment: Evaluates amino acid metabolism, providing insights into metabolic health and disorders.

  • Neurological Disorders: Diagnoses and monitors conditions like serine deficiency and biosynthesis defects affecting brain development.

  • Cancer Biomarker: Indicates tumor growth and progression in cancers such as breast, prostate, and colorectal cancers.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
