Units:

Interpretation:

 RESULTS  INTERPRETATION
 Normal Collagen/Epinephrine (CEPI)  Normal Platelet Function
 Abnormal CEPI with Normal Collagen/ADP (CADP)  Consistent w/Drug Induced Platelet Dysfunction
 Abnormal CEPI with Abnormal CADP  Intrinsic Platelet Dysfunction; Further Studies Indicated

Specimen Requirements:

5.4 mL blood collected in two 2.7 mL LIGHT BLUE top tubes, 3.2% sodium citrate. Analysis is performed on whole blood.

Do NOT refrigerate. Do NOT centrifuge.

Sample must arrive in the lab within 3 hours of draw; the sample is stable only 4 hours after collection.

DO NOT send by pneumatic tube transport.

Pediatric Specimen Requirements:

COL/ADP only: 1 pediatric 1.3 mL LIGHT BLUE top tube, 3.2% sodium citrate.

COL/EPI and COL/ADP: 2 pediatric 1.3 mL LIGHT BLUE top tubes, 3.2% sodium citrate.

Do NOT refrigerate or centrifuge.

Do NOT send via pneumatic tube.

Reference Range:

COL/EPI 85 to 148 seconds

COL/ADP 64 to 113 seconds

Comments:

It is important to note that the PFA-100, like the Bleeding Time test does NOT predict bleeding at surgery, but instead detects defects (often mild) in platelet function. Patients with abnormal tests may have excessive bleeding with trauma, and conversely, a normal test does not preclude excessive hemorrhage.

Patients with low platelet counts (less than 150,000/microliters), low hematocrits (less than 35%) or significantly hemolyzed samples may prolong PFA closure times.

Useful as an initial test when qualitative platelet disorder (congenital or acquired) is suspected (replaces the bleeding time). It may also be useful to monitor new antiplatelet agents, such as GPIIb/IIIa receptor antagonists. 

 PFA  Normal  Aspirin  Von Willebrands Disease  Glanzmanns Disease
 COL/EPI  Normal  Abnormal  Abnormal  Abnormal
 COL/ADP  Normal  Normal  Abnormal  Abnormal

Methodology: PFA-100, aggregation
