Alias Names: ECLT
Methodology: Measurement of fibrinolytic activity of precipitated plasma “euglobulin” fraction
Edit Date: 6/30/2008
Performed: Monday-Friday
Released: Same day
CPT Code: 85360
Specimen Collection Details
Collection: One 4.5 mL light blue top tube (sodium citrate). Collect by careful venipuncture to avoid tissue fluid contamination or hemolysis. Do not use needles smaller than 23 gauge. Fill tube to the maximum draw, at least 90% full. Mix by gentle inversion.
Handling: Due to short stability, specimen must either be sent STAT to arrive at the laboratory within 30 minutes, or sent frozen. For STAT, refrigerate and keep capped in original tube. Call for STAT pick-up. For standard delivery, centrifuge to produce platelet poor plasma (at least 1700 X G for 15 minutes) and with a plastic pipette, transfer plasma to a plastic vial. Freeze immediately. Label with patient name, I.D. number, test, and “citrated plasma.” Send to the laboratory within 7 days. If multiple tests are ordered, freeze a separate aliquot for this test.
Stability: 30 minutes ambient or refrigerated, or 7 days frozen
Standard Volume: 4.5 mL whole blood or 2 mL plasma.
Minimum Volume: 1.8 mL whole blood or 1 mL plasma.
Transport: Whole blood refrigerated; citrated plasma frozen on dry ice.
Comments: Screen for increased fibrinolytic activity in the plasma.
Rejection Criteria: Visible fibrin; any emolysis; specimen received in laboratory beyond stated stability.

Reference Range:
>60 minutes lysis time.
