Test Code
10262

CPT Codes
81265<br /> ** This test code is for non-New York patient testing. For New York patient testing, use test code 10477X.**

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
5 mL whole blood collected in an EDTA (lavender-top) tube

Minimum Volume
3 mL

Other Acceptable Specimens
ACD solution A (yellow-top) • EDTA (royal blue-top) • Sodium heparin (green-top) • Lithium heparin (green-top)

Instructions
Whole Blood: Use normal phlebotomy procedure. Do not transfer to other containers. Specimen stability is crucial. Store and transport ambient immediately. Do not freeze specimens.

Extracted DNA:
Please call 1-866-GENE-INFO (1-866-436-3463) for additional information. This test is run in conjunction with a fetal specimen(Amniotic fluid or CVS). The assay cannot be run until fetal cultures are ready.The TAT is therefore dependent on the TAT of the fetal DNA test on the same patient.

Transport Temperature
Room temperature

Specimen Stability
Room temperature: 8 days
Refrigerated: 8 days
Frozen: Unacceptable

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Received frozen

Methodology
Fragment Analysis by Capillary Electrophoresis • Multiplex PCR

FDA Status
This test was performed using a kit that has not been cleared or approved by the FDA. The analytical performance characteristics of this test have been determined by Quest Diagnostics. This test should not be used for diagnosis without confirmation by other medically established means.

Setup Schedule
Set up: Wed; Report available: 35 days

Reference Range
See Laboratory Report

Clinical Significance
Maternal Cell Contamination Study, STR Analysis, provides assurance that test results from fetal specimens are not influenced by contaminating maternal material. This test also allows for establishing the proper maternal-fetal relationship between specimens by using sophisticated analysis of 15 highly polymorphic STR loci.

Performing Laboratory
Quest Diagnostics Nichols Institute
