What It Is. A partial thromboplastin time (PTT) test measures how long it takes for a clot to form in a blood sample. A clot is a thick lump of blood that the body produces to seal leaks, wounds, cuts, and scratches and prevent excessive bleeding. The blood's ability to clot involves platelets (also called thrombocytes) and proteins called clotting factors.
