Patient's question:
After my daughter was born, the hospital did not give her the BCG vaccine; only the hepatitis B vaccine was administered. When she was enrolled in child health care at one month old, the vaccine list prescribed by the doctor also did not include the BCG vaccine. Now she is 22 days old. Should she receive a? When is the most suitable time? Thank you!Doctor's answer:
The PPD test is a tuberculin test, where tuberculin is injected subcutaneously, and the size of the induration is observed. A result of less than 5 mm is considered negative.The PPD test is a tuberculin test, where tuberculin is injected subcutaneously, and the size of the induration is observed. A positive tuberculin test may indicate that the child has been vaccinated with BCG or that the individual is a tuberculosis patient. No induration or an induration of less than 5 mm is considered negative; an induration of greater than 5 mm but less than 20 mm is considered generally positive. A generally positive PPD test has little diagnostic significance, merely indicating the presence of certain antibodies in the body and requiring no treatment. Your result is 10 mm, and there are no lung lesions, so there is no need to worry.
