头孢类药物皮试液的配制与使用方法（Preparation of cephalosporin skin test and method of use） Preparation of cephalosporin skin test and method of use Preparation of cephalosporin skin test and method of use Allergy status of various domestic studies of cephalosporin allergy test is recommended not penicillin G and cefotaxime try to replace Linpi wow cephalosporins. Recommend skin test if skin test is applied. No matter what the skin test solution preparation of cephalosporin, the method of skin test, skin test results are used to judge the penicillin skin test method. The use of skin test concentration is 300 g/ml, 500 g/ml and 600 g/ml difference. The concentration of 500 g/ml is easy to prepare and more units are adopted. The preparation method is as follows: the cephalosporin 0.5g is dissolved by 10ml injection and dissolved with physiological saline; the liquid medicine 0.1ml is taken; the 0.1ml is diluted with normal saline 10ml; the skin test is carried out; the skin test volume is 50 G. Because the sensitivity of cephalosporin is less than that of penicillin, it is considered that the skin test dose of 50 g is not enough to achieve the purpose of skin test. At present, many departments have increased the skin test dose to 500 mu G. The preparation method is as follows: the cephalosporin 0.5g with 10ml injection with saline solution, the solution 0.1ml, normal saline to 1.0m (or join saline 0.9ml), 0.1ml for skin test, skin test dose is 500 g.
