Specimen requirements | |
|---|---|
| Patient preparation | None Specified |
| Preferred specimen(s) | 10 mL whole blood collected in each of two separate Streck cell-free DNA blood collection tubes |
| Minimum volume | 10 mL |
| Collection instructions | This test requires two Streck tubes. Blood will be collected in office via LiquidSEQ™ Kit for in office and in home draws. Specimens may be shipped separately and at different times. Do not hold blood specimen due to short stability. Do not reject. Blood collection using a straight needle is preferred. All tubes must be filled completely. Gently invert tube at least 8 times immediately after draw. If blood collection is not available in office and providers would like to utilize an in-home draw for blood collection, a mail to home LiquidSEQ kit should be ordered. Simply add test code 13676, "Mobile Phlebotomy Collection, Precision Oncology" with an in-home draw service add test code 18645, "LiquidSEQ kit", to any order containing LiquidSEQ testing. Please note: If an in-home draw is involved, a collection kit will be shipped to the patient. Please note: The LiquidSEQ kit is not required for PSC draws. |
| Transport container | Streck cell-free DNA blood collection tubes |
