Waldman Prob

Waldman sample

The Waldman test (or, as it is also called, the cup test) is one of the methods for studying endothelial function. This method was proposed in 1964 by Vladimir Aleksandrovich Valdman.

The essence of the method is as follows: the patient is injected intravenously with 5 ml of sterile isotonic liquid and 20 minutes after this, blood is taken from the vein for analysis. Then the patient lies on his back, and a needle is inserted into his arm, through which blood will be drawn. After this, the patient is asked to hold his breath for 1 minute.

After this, 5 ml of glucose solution is injected into the needle and blood is taken again for analysis. If the vascular endothelium works normally, the concentration of glucose in the blood will decrease.

Thus, the Waldman test allows you to assess the condition of the vascular endothelium and identify possible disturbances in its functioning. However, this method is not the only one and cannot replace a full examination of the whole body.

Waldman's test is not a very common test. Described by Waldman and Hasler (1963). Currently used only for retrospective diagnosis of cerebral aneurysms due to its low effectiveness. The essence of the test is reduced to intra-arterial stimulation of cerebral circulation in the basilar artery on the side of the suspected aneurysm. The catheter obtained by puncture of the base of the skull is passed through the internal carotid artery at the mouth of the internal carotid vein and fixed under it. In order to create a test aneurysm, the mucous membrane of the lower pole of the right maxillary sinus is punctured through the wall separating it from the lateral wall of the brain
