25520:COAGULATION STUDY, D.I.C. SCREEN
Alias Names: D.I.C. SCREEN
Methodology: Photo-Optical Clot Detection; Latex Bead Agglutination
Edit Date: 4/6/2005
Components: Activated Partial Thromboplastin Time (APTT) / D-Dimer, Quantitative / Fibrinogen; Hemoglobin and Platelet Count / Prothrombin Time (PT) / Interpretation
Performed: Daily
Released: Same day for most tests. Interpretation: Next day.
CPT Code: 85027 / 85379 / 85384 / 85610 / 85730
Specimen Collection Details
Collection: One 4 mL lavender top tube (EDTA) AND one 4.5 mL light blue top tube (sodium citrate). Collect by careful venipuncture to avoid tissue fluid contamination or hemolysis. Do not use needle smaller than 23 gauge. Fill light blue top tube to maximum draw, at least 90% full. Mix by gentle inversion.
Handling: Due to short stability, specimens must either be sent STAT to reach laboratory within 4 hours, or sent frozen. For STAT, refrigerate and keep capped in the original tube. For standard delivery, centrifuge light blue top tube to produce platelet-poor plasma (at least 1700 x G for 15 minutes), and with a plastic pipette, transfer to a plastic tube. Label with patient name, I.D. number, test, and “plasma.” and freeze immediately. Send to laboratory within 7 days.
Standard Volume: 4 mL lavender top tube (EDTA) and 4.5 mL light blue top tube (sodium citrate).
Minimum Volume: 1 mL lavender top tube in microcollection tube, and 2.7 mL light blue top tube (sodium citrate) or 1.5 mL plasma.
Transport: Original tubes refrigerated if sent STAT; plasma frozen on dry ice.
Rejection Criteria: Clotting; visible fibrin strands; moderate to marked hemolysis; specimen received in laboratory beyond stated stability.
