Specimen Requirements
Collection Instructions

Collect blood in a lavender top tube. Refrigerate and send intact blood specimen within 48 hours of collection.

Special Handling

To reduce inappropriate thrombophilia testing in the inpatient population this test has been removed from the inpatient test catalog. If there is a specific clinical need for this test on an inpatient please contact the Coagulation Laboratory.

Alternate Specimen
The preferred specimen is whole blood collected in EDTA (lavender top). All other anticoagulants will not be accepted.
Contraindications
In the absence of specific information regarding advances in the knowledge of mutation characteristics for a particular disorder, the current literature indicates that genetic tests for inherited disease need only be conducted once per lifetime.
Lavender Top Tube
Normal Volume
5 mL EDTA (lavender) whole blood
