Pathology: Blood or qi deficiency. This is seen in cases of deficiencies and failure of Qi and blood. It can also be seen in disharmonies of the even emotions, weakness in Yang Qi, internal damage to jing, and penetration of dampness.
Testing for venous blood clots. Venous blood clots may be detected in a variety of ways, though ultrasound is most commonly used. Occasionally, the patient's size and shape limit the ability for ultrasound to provide a definitive answer. Venography is an alternative test to look for a clot.
Thatâs how itâs supposed to work. When it doesnât, you may find that you bleed or bruise easily or that you get clots in your blood vessels when you shouldnât. Thatâs when your doctor might order a partial thromboplastin time (PTT) test, which measures how many seconds it takes for your blood to clot. What Does a PTT Test Look For? Your body makes several different clotting factors. A problem with any of them -- if itâs missing, broken, or you donât have enough -- can affect how long it takes a clot to form, if it forms at all. A PTT test looks at one set of these factors to see how well theyâre working. Itâs often done along with another test, called the prothrombin time (PT) test, which looks at another set of clotting factors.
