HelpTest ID PSYQP Psychotropic Pharmacogenomics Gene Panel, Varies
Necessary Information
Prior Authorization is available, but not required, for this test. If proceeding with the prior authorization process, submit the required form with the specimen.
Specimen Required
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 whole blood 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 Volume: 2 Swabs, use 2 kits for collection
Collection Instructions: Collect and send specimen per kit instructions.
Additional Information: Due to lower concentration of DNA yielded from saliva, testing cannot proceed to reflex testing for CYP2D6 sequencing and will stop after initial testing is complete.
Specimen Stability Information: Ambient 30 days
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. Provide concentration of DNA 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
Testing Algorithm
If a specimen requires follow-up for CYP2D6, then reflex testing will be performed as appropriate at an additional charge.
