Generally, the four-item infectious disease screening primarily includes testing for antibodies against hepatitis B virus, hepatitis C virus, human immunodeficiency virus (HIV), and syphilis. This screening is performed via blood draw. If any discomfort occurs, it is recommended to seek medical attention promptly. Specific details are as follows:
In most medical institutions, when conducting the four-item infectious disease screening, doctors issue a blood test request form, and trained healthcare professionals collect a certain amount of blood sample through venipuncture. Blood testing allows simultaneous detection of multiple infectious diseases from a single blood draw and can accurately detect the presence of specific antibodies or antigens in the body, offering relatively high accuracy.
Before undergoing any health examination, it is advisable to consult a qualified physician to understand the specific testing procedures and precautions, ensuring accurate test results.
