Plasmodium antibodies and antigens

Refers to the detection of antigens and antibodies in the blood after Plasmodium infection. This test is used for the diagnosis of malaria. Immune antibodies can be detected 1 week after the infection with protozoa, and reach a peak in a short period of time. After a period of time, the titer drops until it disappears. The level of antibody titer is related to the individual's immune response, whether there is repeated infection, and whether the treatment is thorough. Since antibodies are produced after protozoa, clinically, Plasmodium antibodies have no early diagnostic value for the first-time patients; for multiple cold episodes without identifying the cause, detection of Plasmodium antibodies will be helpful in diagnosis. The main value of antibody testing lies in the epidemiological investigation of malaria, including understanding the endemic level of malaria, monitoring the intensity of transmission, determining the scope, and assessing the effects of prevention and treatment. Basic Information Specialist classification: Infectious disease examination and classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours, so as not to affect the test results. Normal value The indirect immunofluorescence method is less than 1:20. Enzyme-linked immunosorbent assay and radioimmunoassay were negative.

Positive results may be diseases: malaria, chronic bacterial dysentery matters needing attention Before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. After inspection: 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. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process Inspection method: draw blood. Not suitable for the crowd There are no special taboos. Adverse reactions and risks There are no related complications and hazards.
