Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | Serum and EDTA Whole Blood | Red Top Tube (RTT) and EDTA Lavendar Top Tube (LTT) | 3.0 mL (RTT) and 5.0 mL (LTT) | 1.0 mL (RTT) and 2.0 mL (LTT) |
Collection/Processing Instructions
Centrifuge and remove serum from cells within one hour.
Test panel includes bilirubin which is light sensitive, minimize light exposure during storage/transport.
Prepare 2 blood smears as soon as possible, preferably within two hours of collection, up to 24 hours, label with computer generated label or use pencil to label with patients full name and date. Store slides at room temperature.

| Serum, Whole Blood | Refrigerate | <48 hours |
| Whole Blood | Ambient | <24 hours |
| Whole Blood | Refrigerate | >48 hours may be reported with additional comments |
| Blood slides (smears) | Ambient | <30 days |
Rejection Criteria
| Grossly hemolyzed samples |
|---|
| Clotted whole blood |
| Frozen whole blood |
| Serum specimens not separated from cells <2 hours |
| Whole blood diluted with IV or tissue fluid |

Test Information
Medicare patients must sign a waiver before specimen is collected since Medicare considers this a non-covered screening panel. Individual tests ordered for diagnostic purposes are covered.
Interferences
Hemolyzed samples will falsely increase K and AST
Exposure to light will falsely decrease TBIL
