HIV (p24) HIV home testing and treatment in the USA
HIV and AIDS
HIV is transmitted via sexual contact and body fluids, normal social contact between individuals don't transfer the infection. The human immunodeficiency virus (HIV) will develop into AIDS if not treated with medication. The early stage of HIV infection is the most infectious and also mostly undetected by the carrier. The first symptoms of HIV infection can easily misinterpret as the flu, HIV (p24) Antigen home test kit will tell you in an early stage if you are infected or not.
No symptoms.The most common is to not get any symptoms associated with that you get HIV. How long it then takes until you feel that you have HIV varies from person to person, but it could be several years. During that time usually feel as usual and did not notice anything of the infection. HIV (p24) Antigen Home Test.
Early SymptomsApproximately two to three weeks after getting HIV to get some so-called primary HIV infection. Then you can for example get
- a sore throat
- swollen, tender lymph nodes
- a headache
- bright red, irregular rash on his back and chest, and sometimes the face, arms and legs.
- The early symptoms disappear by themselves, usually within a few weeks.
How long it then takes until you notice something more varies from person to person, but it could be several years. During that time usually feel as normal.
Late SymptomsAfter a long period of time, usually several years, you get the first signs that your immune system is weakened. It may prove that
- night sweats
- dandruff Eczema on Face
- fungus in the mouth.
If the immune system becomes even more impaired you can get tumors or severe infections with bacteria, fungi or parasites. This type of infection is rare in people who have a healthy immune system. It is the condition known as AIDS. HIV (p24) Antigen Home Test
HIV (p24) Home Self-test Blood Sample
screening tests to detect p24 antigen to HIV type 1 only 3 to 6 weeks post exposure
A rapid test for the diagnosis of Human Immunodeficiency Virus to detect p24 antigen to HIV type 1 qualitatively in Whole Blood Sample. For Home in vitro diagnostic use only.
The HIV p24 Antigen Rapid Test Cassette (Whole Blood Sample) is a rapid chromatographic immunoassay for the qualitative detection of p24 antigen to Human Immunodeficiency Virus (HIV) type 1 in whole blood, to aid in the diagnosis of HIV infection
The HIV p24 antigen is a small piece of protein that is found on the capsule of the HIV virus. When a person is infected with HIV, these bits of protein can be found floating in the blood. The HIV p24 antigen rapid test is the test that detects these bits of protein. This test was first developed as a HIV screening test but rapidly ran out of favor due to the development of more advanced NAAT tests1.
The window period for p24 testing is also very small. This test alone is only accurate for between 3 and 6 weeks post exposure. So it is a test with very limited applications unless combined with HIV type 1 and 2 - 4th Generation Antibody IgG /IgM home test. The presence of p24 antigen in the blood indicated a recent HIV infection.
The HIV p24 Antigen Rapid Test Cassette (Whole Blood Sample) is a rapid test to qualitatively detect the presence of p24 antigen to HIV 1 in whole blood, serum or plasma specimen. The test utilizes latex conjugate HIV p24 antibody to selectively detect p24 antigen to the HIV type 1 in whole blood sample.
The HIV p24 Antigen Rapid Test Cassette (Whole Blood/Serum/Plasma) is a qualitative, membrane-based immunoassay for the detection of p24 antigen to HIV type 1 in whole blood, serum or plasma. The membrane is pre-coated with mouse anti-HIV p24 antibody. During testing, the whole blood, serum or plasma specimen reacts with HIV p24 antibody-coated particles in the test Cassette.
The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with HIV p24 antibody on the membrane in the test line region. If the specimen contains a p24 antigen to HIV type 1, a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain a p24 antigen to HIV type 1, a colored line will not appear in the test line region, indicating a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
The test contains HIV type 1 p24 antibody-coated particles and anti-HIV p24 antibody coated on the membrane
A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
Control standards are not supplied with this test Cassette; however, it is recommended that positive and negative controls be tested as a good laboratory practice to confirm the test procedure and to verify proper test performance
The HIV p24 Antigen Rapid Test Cassette (Whole Blood sample) is for in vitro diagnostic use only. The test should be used for the detection of HIV p24 antigen in whole blood, serum or plasma specimens only. Neither the quantitative value nor the rate of increase in HIV p24 antigen can be determined by this qualitative test.
The HIV p24 Antigen Rapid Test Cassette (Whole Blood/Serum/Plasma) will only indicate the presence of p24 antigen to HIV type 1 in the specimen and should not be used as the sole criteria for the diagnosis of HIV infection
If the test result is negative and clinical symptoms persist, additional testing using other clinical methods is recommended. A negative result does not at any time preclude the possibility of HIV infection.
Sensitivity and Specificity
TheHIV p24 Antigen Rapid Test Cassette (Whole Blood Sample) has been compared to a leading commercial ELISA HIV test using clinical specimens. The results show that the relative sensitivity of the HIV p24 Antigen Rapid Test Cassette (Whole Blood Sample) is 96.7% and the relative specificity is 99.3%.
Relative sensitivity: 96.7% (95%CI*: 82.8%~99.9%);
Relative specificity: 99.3% (95%CI*: 97.6%~99.9%);
Accuracy: 99.1% (95%CI*: 97.4%~99.8%).
Within-run precision has been determined by using 15 replicates of four specimens: a negative, a low positive, a medium positive and a high positive. The negative, low positive, medium positive and high positive values were correctly identified >99% of the time.
Between-run precision has been determined by 15 independent assays on the same four specimens: a negative, a low positive, a medium positive and a high positive. Three different lots of the HIV p24 Rapid Test Cassette (Whole Blood sample) have been tested over a 3-day period using negative, low positive, medium positive and high positive specimens. The specimens were correctly identified >99% of the time.
The HIV p24 Rapid Test Cassette (Whole Blood sample) has been tested by HAMA, RF, HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, HCV, Syphilis, H. Pylori, MONO, CMV, Rubella and TOXO positive specimens. The results showed no cross-reactivity.
The following potentially interfering substances were added to HIV negative and positive specimens.
|Acetaminophen: 20 mg/dL||Caffeine: 20 mg/dL|
|Acetylsalicylic Acid: 20 mg/dL||Gentisic Acid: 20 mg/dL|
|Ascorbic Acid: 2g/dL||Albumin: 2 g/dL|
|Creatin: 200 mg/dL||Hemoglobin: 1.1 mg/dL|
|Bilirubin: 1g/dL||Oxalic Acid: 600mg/dL|
None of the substances at the concentration tested interfered in the assay.
