Must be an inpatient at MidMichigan Health - Midland. Specimen must arrive unspun to the lab within 15 minutes of draw.
The TEG (Thromboelastograph) analyzer measures a clot's properties using a small cup that holds the blood and slowly oscillates. A pin, held by a thin wire, is suspended in the blood. When the clot forms, it links the pin and cup together and the torsion of the pin is measured and converted to electrical signals which are monitored by a computer.
RTEG = 5-10 minutes
KTEG = 1-3 minutes
ANGLE = 53-72 degrees
MATEG = 50-70 mm
