Common examination of compressive urticaria

1. Histamine challenge test

Histamine provocation test is to use histamine to induce paroxysmal hypertension patients without attack and low blood pressure. Before the trial, sedative drugs should be stopped for 3 days and antihypertensive drugs should be stopped for 2 weeks. If blood pressure > 21.3/14.6 kPa (160/110 mmHg), this trial should not be conducted. Phentolamine should be available during the test for use when blood pressure is too high. People with allergy and asthma should not do this test. This test is in danger of causing extreme blood pressure increase, so it should be very careful. 3. Basophil count

2. Blood routine

Blood test is to detect and analyze the quantity and quality of the three systems, namely red blood cells, white blood cells and platelets. These three systems and plasma constitute blood, which constantly flows in the circulatory system of human body and participates in metabolism and every functional activity of human body. Therefore, blood plays an important role in ensuring metabolism, functional regulation and balance of internal and external environment of human body. Pathological changes of any visible components in blood will affect tissues and organs of the whole body; On the contrary, the pathological changes of tissues or organs can cause changes in blood components, so hematological analysis and its results are of great help to understand the severity of diseases. Most hospitals use automated hematology analyzers for routine blood tests (now called hematological analysis). Only 0.1 ml (about two drops of blood) of anticoagulation is needed for each examination, and more than 20 results can be detected and printed in 30 seconds or 1 minute.
