The target antigen (Sa antigen) was first found in the human spleen and then found in human placenta and rheumatoid synovium, which may be the normal tissue component of the human body. Analysis by immunoblotting technique showed that the molecular weight of Sa antigen in human spleen was 50 kD, while that of human placenta was 50 and 55 kD. Basic Information Specialist classification: growth and development check classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Normal human anti-Sa antibody is negative.

Precautions Before the exam: relax and not be overly nervous. When checking: Actively cooperate with the doctor. Inspection process The cells in the spleen or placental cells were taken and analyzed by immunoblotting. Actively cooperate with doctors. Not suitable for the crowd There are no taboos.
