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.
