The difference was significant(P〈0.01). Conclusions 0.5% iodophors has no stimulation to skin and doesn’t affect the judgment of skin test result and can decrease the incidence of false positive cases in penicillin skin test in children, so it can be used as skin disinfector in penicillin skin test.
It introduced the influence of the preparing method, dose, concentration of tetanus antitoxin skin test fluid and selecting of location skin test on assessment of skin test result. It explained announcements for using TAT in clinical practice.
Results Out of the 56 cases that were tested with 28 items of food allergen, 52 cases (92.9%) showed positive skin test on more than one item with the intensity of "+"-"+++", and four cases (7.1%) gained negative skin test findings.
Result: There is significant difference in positive rate between the two groups with ionic iodinated contrast (P <0.01), the people who are negative in the experimental group and positive in contrast group accept intravenous injection have negative results. The positive rate is 74.71% in the people who is positive in the experimental group then accepted intravenous injection.
to strictly master the injection techniqu, e of tetanus antitoxin. Result: To use the new methods for doing TAT skin test ,the positive rate is only 7.2% and after desensitization injection for the 7.2% patients . We get injection rate of 99.88%.
