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.
A D-dimer test is one way a doctor can see whether you have a serious blood clot. When you get a cut, your body takes a bunch of steps to make your blood clump up. Itâs a normal part of healing -- without it, youâd keep bleeding and have a much more serious problem to deal with.
