| VERIFYNOW PRUtest (LAB 002086) | |
|---|---|
| Test Mnemonic: | Prutest; P2Y12 |
| Specimen Requirements: | Whole blood
|
| Collection: | Sample MUST be collected in kit provided by the Laboratory . Do not shake. Hand deliver specimen. Do NOT send through tube system. Use 2 mL Greiner Bio-One partial-fill vacuette tubes with 3.2% sodium citrate (blue top). Collect 2 tubes of whole blood using a 21 gauge or larger needle. First, collect a discard tube (at least 2 mL) making sure the discard tube does not contain any platelet inhibiting substance (e.g. EDTA). Butterfly (21 gauge) is OK to use. Fill the second tube and thrid (sample tube) to the black line (1/2 tube). Do not under fill. Discard the first tube, and keep the others for testing. If drawing blood for a CBC at the same time, fill the CBC tube last. Gently invert the tube at least 5 times to ensure complete mixing of the contents. Do not shake, as that may give incorrect results. Label the tube with the patient ID, date and time it was drawn. Do not refrigerate. Indwelling Catheter collection: Discard the first 5 mL from an indwelling catheter to clear the line. Ensure the catheter is free of clots. Immediately transfer blood to a 2 mL Greiner Bio-One partial fill vacuette tube with 3.2% sodium citrate (blue top). Fill to the black line (1/2 tube). Do not under fill. If drawing blood for a CBC at the same time, fill the CBC tube last. Gently invert the tube at least 5 times to ensure complete mixing of the contents. |

| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
