Hereditary Interstitial Kidney Disease (UMOD) DNA Sequencing Test
Test Code93750
CPT Codes
81406<br>Limited Access Code
Physician Attestation of Informed Consent
This germline genetic test requires physician attestation that patient consent has been received if ordering medical facility is located in AK, DE, FL, GA, IA, MA, MN, NV, NJ, NY, OR, SD or VT or test is performed in MA.
Preferred Specimen
8 mL whole blood collected in EDTA (lavender-top) tubes, or
Pediatric 0-3 years: 2 mL whole blood
Pediatric 0-3 years: 2 mL whole blood
Minimum Volume
6 mL • 1 mL pediatric
Instructions
Informed consent is required.
Please label each specimen tube with two forms of patient identification. These forms of identification must also appear on the requisition form.
Ship room temperature, avoid freezing.
Higher blood volumes ensure adequate DNA quantity, which varies with WBC, specimen condition, and need for confirmatory testing. Patients, 0-3 years have higher WBC, yielding more DNA per mL of blood.
