LaboratoryClotting time of Capillary blood by Sukharev method
Definition
The Sukharev clotting time uses capillary blood and a test tube called the Panchenkov's device that is manually tilted every 30 seconds until the blood clot has formed. The tube has a diameter of 1mm and the reference range is 2-5 minutes. In contrast, the Lee White method, which is also manual, uses a tube with a diameter of 8-10mm, which results in a larger volume of blood and longer testing time with a reference range of 5-10 minutes.
