HIV positive person: HIV infected person. After HIV invades the human body for a certain period of time, HIV antibodies will be detected in the blood. If a person detects HIV antibody, it is confirmed that he is infected with HIV.
Positive: what can be detected is positive, and what cannot be detected is negative.
HIV negative: two possibilities, 1. No HIV infection; 2. Infected with HIV, but no antibodies are produced in the body (window period)
What are RH positive and RH negative? Characteristics of (1): There are no natural antibodies in Rh-positive and Rh-negative blood, but if Rh-negative blood receives Rh-positive blood, under the influence of Rh antigen, anti-Rh antibodies can appear in Rh-negative human serum. When Rh-negative people receive Rh-positive blood again, the existing anti-Rh antibody in their serum will agglutinate with the imported Rh antigen, which is the first point of clinical significance of Rh blood group. (2) The second clinical significance of 2)Rh. If a Rh-negative woman gives birth to a Rh-positive fetus, the Rh antigen of fetal red blood cells may enter the mother through the placenta during delivery, and the mother will produce anti-RH antibodies. When the mother gives birth to a Rh-positive fetus again, the mother's Rh antibody (IgG can pass through the placenta) enters the fetus through the placenta and combines with the Rh antigen of fetal red blood cells, resulting in fetal hemolysis. Blood type is the genetic symbol of human beings. What is on the surface of blood cells is usually called blood group antigen. There are hundreds of blood group antigens on red blood cells, white blood cells and platelets, and the combined blood group exceeds 10 17, which has exceeded the total population of the earth. Theoretically, no two people have the same blood type except identical twins. Usually refers to red blood cell blood type, refers to ABO blood group system, there are four blood types: A, B, O and AB. The classification principle is to see whether there are type A and type B antigens on red blood cells, that is, only type A antigens are called type A; Only antigen b is called type b; Without a and b, it is called type o; Those with A and B are called AB type. Blood type can be inherited, that is, everyone has two genes: type A is AA or AO; Type b is BB or bo; Type o is oo; Type AB is AB. Parents each pass a gene to their children to form their blood type, so the blood type of their children can be inferred from their parents. For example, parents of type A and type O may have children of type A and type O, or they may not have children of type B and type AB; Parents of type A and type B can give birth to children with four blood types: A, B, O and AB. ABO blood group has the greatest relationship with blood transfusion, followed by Rh blood group. Rh blood group can be divided into positive and negative, and people with Rh negative can only transfuse Rh negative blood, otherwise there will be serious reaction. Rh negative rate of Han nationality in China was 0.4%; 5 ~15% of ethnic minorities of white descent are RH negative. Pay special attention to blood transfusion.
What do you mean by masculine and feminine? -On the inspection report, negative results indicate that no specific substance or microorganism has been detected (or the detection amount is small), positive results indicate that it has been detected, and strong positive results indicate that the detection amount is large. For example, the detection of two and a half pairs of hepatitis B includes five indicators, which respectively represent a substance (the antigen is the protein of the virus, and the antibody is the protein produced by your own reaction to the antigen), and a positive one means detection. The pregnancy test stick you are talking about is to detect chorionic gonadotropin (HCG), which can be detected in the urine on the seventh day of pregnancy. It is chorionic gonadotropin that produces the placenta. If this test is positive, it means that HCG has been detected, probably pregnant, but it may also be other diseases. If it is negative, it means that it has not been detected, but it does not mean that it must not be pregnant!
-Negative on the physical examination form means that no abnormal symptoms are found, and positive means that there are abnormal symptoms (in most cases).
If in doubt, consult a professional doctor!
What is hpv positive and HPV negative human tumor virus, that is, human papillomavirus, which is the main cause of cervical cancer? There are many subtypes of human tumor virus, and high-risk human tumor virus refers to the subtype with high risk of inducing cervical cancer. Cervical cancer can be controlled and treated at an early stage through detection and screening, and regular screening is recommended.
TPPA negative, trust positive, anti-HIV negative, what do you mean? TPPA negative, trust positive.
TPPA is negative, which means the syphilis test is negative. This is a confirmation test.
Trust is positive, indicating that syphilis screening test is positive, which may be caused by other factors.
Anti-HIV antibody is negative, indicating that there is no preliminary test for AIDS.
What do you mean by negative trust and tppa? Hello, TPPA has detected the antibody of Treponema pallidum. Only when TPPA and TRUST or RPR are positive at the same time, the diagnosis is meaningful. TPPA is mainly used to observe AB titer after infection or treatment. TPPA is accompanied for a long time, can occur for life and has a low titer. , view the original post >>
What do you mean by hbsag positive, hcv-ab negative and hiv-ab negative? AIDS is a virus. Only by blocking virus replication with antiviral drugs can it not be killed. This is why AIDS cannot be cured.
The difference between HIV negative and HIV positive
For AIDS patients, routine blood tests are particularly important. Because 30% ~ 40% patients are often accompanied by anemia, leukopenia, lymphopenia and thrombocytopenia. The whole blood cell count should be repeated every 3 ~ 6 months, which is an integral part of CD4 cell count monitoring to some extent. For patients who use bone marrow suppression drugs (such as AZT), their blood cell count is at marginal or low level, and they have symptoms of bone marrow suppression, so the detection frequency should be increased.
On the contrary, it is negative
What is HBsAg positive +HBsAb negative +HBeAg negative +HBeAb negative +HBcAb positive +HBc-IgM negative +PS 1 positive? Xiaoeryang
There is a certain virus replication.
