Official title

Bleeding Volume Test: A Double-Blind Crossover Randomized Clinical Trial of an In-Vivo On-Line Test for Aspirin Effect and Resistance

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Purpose of the present research project is to study a new in-vivo test for abnormal platelet function and to study the effect of certain drugs on clinical bleeding. This is a randomized clinical trial of a new in-vivo test of platelet function known as the bleeding volume test(BVT)which relies on an on-line measurement system. This trial will assess the sensitivity and specificity of the new BVT by studying the effects of aspirin which is known to affect platelet function in-vivo. This is not a clinical trial of drugs. This is a clinical trial of a novel in-vivo on-line laboratory test. The BVT measures the total volume of blood in the discrete blotches of blood on the blotter paper during the BT test and thus the BVT gleans valuable additional information from the bleeding time test (BTT)procedure. We hypothesize that the BV test will be a more accurate, specific and sensitive test for diagnosing platelet function abnormalities and for detecting a person's bleeding tendency compared to the BTT, and commercially available in-vitro platelet function tests.
