Test Code LAB3549 ADAMTS 13 Activity and Inhibitor
Additional Codes
ADAMTS13
Clinical System Name
ADAMTS 13 Activity and Inhibitor
Synonyms
ADAMTS–13 Inhibitor Assay; ADAMTS–13 Protease Activity; ATS-13; VWF Cleaving Protease Activity + Inhibitor
Sample Requirements
Specimen: Whole Blood
Container(s): Lt. Blue/Citrate
Preferred Vol: (3) 1.8 mL or (1) 2.7 mL
Minimum Vol: (2) 1.8 mL
Note: Preferred method of collection is venipuncture with vacuum fill. Test results are affected by incorrect blood volume. Use of a Vascular Access Device for the collection of coag testing is not recommended.
If this method is used it requires a 5 cc clearing volume; 3 cc for size 2 French catheter or smaller. Blood must be trasferred to the Lt Blue/Citrate tube by use of a blood transfer device to ensure proper fill.
Specimen should be centrifuged within ONE hour of collection.
