Ristocetin Cofactor Test
Introduction
The Ristocetin Cofactor Test is a vital diagnostic tool used primarily to assess platelet function in patients suspected of having bleeding disorders. This test measures the ability of platelets to agglutinate in the presence of ristocetin, a specific antibiotic that enhances the interaction between von Willebrand factor and platelets. Accurate and timely diagnosis is crucial in managing thromboembolic disorders, making this test invaluable in clinical settings.
What the Test Measures
This test specifically measures the cofactor activity of von Willebrand factor, which is essential for platelet adhesion. It helps in identifying deficiencies or dysfunctions in this factor, which can lead to increased bleeding risk.
Who Should Consider This Test?
Individuals who may benefit from the Ristocetin Cofactor Test include:
- Patients with unexplained bleeding tendencies.
- Individuals with a family history of bleeding disorders.
- Patients diagnosed with von Willebrand disease.
- Individuals undergoing pre-surgical assessments.
Benefits of Taking the Test
- Accurate diagnosis of bleeding disorders.
- Guides treatment decisions and management strategies.
- Helps in pre-operative evaluations to prevent complications.
Understanding Your Results
Results from the Ristocetin Cofactor Test will indicate whether your platelets function normally in the presence of ristocetin. A low result may suggest von Willebrand disease or other related disorders. It is essential to discuss your results with a healthcare provider for appropriate interpretation and guidance.

Sample Collection and Pre-Test Instructions
For the Ristocetin Cofactor Test, a sample of 3 mL whole blood must be collected in a blue top (sodium citrate) tube. It is crucial to:
- Mix the sample thoroughly by inversion.
- Transport to the lab within 4 hours.
- If transport is delayed, prepare platelet poor plasma (PPP) by centrifuging the sample at 3600 rpm for 15 minutes.
- Transfer the supernatant to a clean plastic tube and freeze immediately.
Overnight fasting is mandatory, and a duly filled Coagulation Requisition Form (Form 15) and Test Send Out Consent Form (Form 35) are required.
