COMT Genetic Test
- COMT Genotype
Expected Turnaround Time
8 - 21 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Whole blood or LabCorp buccal swab kit (buccal swab collection kit)
1 mL (Note: This volume does not allow for repeat testing).
Lavender-top (EDTA) tube, yellow-top (ACD) tube, or LabCorp buccal swab from kit
Causes for Rejection
Frozen sample, hemolysis; incorrect collection kit
COMT alleles have been associated with disease risk or drug responsiveness (e.g. early vs. late Parkinson's disease, schizophrenia, chronic pain conditions). The COMT genotype plays a role in cognition and behavioral modification (e.g. smoking cessation, modafinil responsiveness in sleep deprivation and addiction treatment), and potentially influences estrogen-related conditions (e.g. breast cancer risk when taking hormone replacement therapy, recurrent preeclampsia).
Only the 6 SNPs in question are tested; polymorphisms or some sequence variants might affect efficiency of the PCR or mini-sequencing assays. Haplotype phases are inferred based on our validation studies. Donor DNA from transplants and recent transfusions can lead to inaccurate results.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
