contact us· This test can help determine whether the cause of Cushing syndrome is rooted in the pituitary or somewhere else. For the test, blood samples are taken from the veins that drain the pituitary gland (petrosal sinuses). A thin tube is inserted into your upper thigh or groin area while you''re sedated and is threaded to the petrosal sinuses.
contact usAggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined.
