Necessary Information


Psychotropic Pharmacogenomics Gene Panel Prior Authorization Ordering Instructions is required. See Special Instructions.



Specimen Required


Prior Authorization is available for this test. Submit the required form with the specimen.

 

Submit only 1 of the following specimens:

 

Specimen Type: Whole blood

Container/Tube: Lavender top (EDTA)

Specimen Volume: 3 mL

Collection Instructions:

1. Invert several times to mix blood.

2. Send specimen in original tube. Do not aliquot.

Specimen Stability Information: Ambient (preferred) 9 days/Refrigerated 30 days

 

Specimen Type: Saliva

Patient Preparation: Patient should not eat, drink, smoke, or chew gum 30 minutes prior to collection.

Supplies: Saliva Swab Collection Kit (T786)

Specimen Type: Extracted DNA

Container/Tube: 2 mL screw top tube

Specimen Volume: 100 mcL (microliters)

Collection Instructions:

1. The preferred volume is 100 mcL at a concentration of 50 ng/mcL.

2. Include concentration and volume on tube.

Specimen Stability Information: Frozen (preferred) 1 year/Ambient/Refrigerated

Useful For

Individualizing selection and dosage of medications prescribed for treatment of depression and other psychiatric disorders based on genetic variation

 

Identifying genetic variation in genes known to be associated with response and/or risk of toxicity with psychotropic medications

 

Evaluating patients who have failed therapy with selective serotonin reuptake inhibitors (SSRI)

 

Evaluating patients with treatment-resistant depression

 

Predicting response time to improvement with SSRI

Genetics Test Information

This test includes targeted testing to evaluate the following genes: ANKK1, ADRA2, CHRNA3, COMT, CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, CYP3A5, DRD2, EPHX1, GRIK4, HLA-A*31:01, HLA-B*15:02, HTR2A, HTR2C, MTHFR, OPRM1, SCN1A, SLC6A4 (5-HTT), UGT2B15.

 

CYP2D6 testing is done in 2 tiers when needed. Tier 1 uses a polymerase chain reaction (PCR)-based 5'-nuclease assay to determine the variants present. All samples also have copy number determined by PCR-based 5'-nuclease assay. Testing in tier 1 allows for the detection of all common CYP2D6 variants (eg, *2, *3, *4, *5, *6, *7, *8, *9, *10, *17, *29, *35, *41) and rarer alleles such as *11, *12, *14, *15, and *114. Duplications and multiplications of alleles are also identified. Unitary and tandem CYP2D7-2D6 (*13) alleles and CYP2D6-2D7 (eg, *4N, *36, and *68) alleles can also be detected. Tier 2 testing involves sequencing using fluorescent dye-terminator chemistry and is only done if an ambiguous phenotype results from tier 1 testing. Approximately 3% of samples require tier 2 testing.

 

Prior Authorization is available for this assay; see Special Instructions.

Testing Algorithm

If a specimen requires follow-up for CYP2D6, then reflex testing will be performed as appropriate at an additional charge.
