Test Code LAB6929 TEG PLATELET MAPPING

Important Note

Due to limited sample stability outpatient collection needs to take place in the KH hospital laboratory.

Specimen Requirements

Green top tube (lithium heparin with no gel) filled completely by vacuum

 

Venipuncture: Use a 21 gauge needle or larger. Drawing a discard tube with no additive or discard syringe of 3-5 mL prior to collecting blood is strongly recommended. Suitable discard tubes include no additive tubes or a blue top marked "discard." After collection, gently invert the tube 5 times to mix.

Line Draw: When drawing from a line, be sure to use plastic syringes that are not heparinized. Using two syringes, discard 3x's the dead space (typically 10 mL). Using a safe transfer device (or a standard needle no smaller than 21 gauge), allow the blood collection tube to fill completely by vacuum. After collection, gently invert the tube 5 times to mix.

Specimen Processing

Dark green top tube filled to capacity. Must be performed within 2 hours of collection.
