In particular, Turner syndrome is a genetic disease in which only one X chromosome is involved in a sex chromosome. (Normal male sex chromosomes should be XY two, normal female sex chromosomes are XX two) Klinefelter syndrome, sex chromosome is a genetic disease of XXY. This type of patient has both male and female characteristics. Sheen syndrome (also known as Sheehan syndrome), translated from Sheehansyndrome, is a series of diseases caused by hypothalamic necrosis of the pituitary gland and decreased secretion of hormones. Low results may be diseases: Sheen syndrome results are high, may be diseases: amenorrhea considerations First, the precautions before blood draw 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking.

Second, should pay attention after blood draw 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4.
