It has been reported that blood trombopoietin (TPO) levels can discriminate between thrombocytopenia due to increased platelet destruction and decreased platelet production. Platelets, also known as thrombocytes, are tiny, round cell fragments which circulate in your blood and are essential for the formation of blood clots. A citrated whole blood sample is aspirated from a reservoir and run through biological membranes with a central aperture. This plug is called a blood clot. A down-trending platelet count is often the first laboratory abnormality which to be noted. Heparin-induced thrombocytopenia (HIT) is a clinical-pathological disorder; thus, laboratory testing for the pathogenic platelet-activating antiplatelet factor 4 (PF4)/heparin antibodies is central for diagnosis. Lab values are used to determine a patient’s overall health and well-being.
