Trousseau And Chvostek Signs. Chvostek s sign is very easy to test in clinical practice compared with trousseau s sign and hence its clinical significance. Thus this test while suggestive is not diagnostic of hypocalcemia 4. Although the two signs have never been compared directly it is believed that the trousseau sign is more specific for hypocalcemia than the chvostek sign. In one study 94 of patients with confirmed hypocalcemia had a positive trousseau sign whereas only 1 of healthy patients showed a positive trousseau sign.
Physical examination revealed apparent chvostek s sign figure 1a and video 1 and trousseau s sign figure 1b and video 2 a result of postsurgical acquired hypoparathyroidism. Chvostek s sign is very easy to test in clinical practice compared with trousseau s sign and hence its clinical significance. Although the two signs have never been compared directly it is believed that the trousseau sign is more specific for hypocalcemia than the chvostek sign. Thus this test while suggestive is not diagnostic of hypocalcemia 4. However up to 10 of the population will have a positive chvostek sign in the absence of hypocalcemia. In one study 94 of patients with confirmed hypocalcemia had a positive trousseau sign whereas only 1 of healthy patients showed a positive trousseau sign.
