Description
The HBsAg, HCV, HIV & Syphilis Rapid Test Combo is a rapid visual immunoassay for the qualitative, presumptive detection of HBsAg, antibodies to HCV, antibodies to HIV- 1/HIV-2 and antibodies to Treponema Pallidum (TP) in human whole Blood, serum or plasma specimens.
For professional use only.
For in vitro diagnostic use only.
Hepatitis B virus (HBV) is the prototypic member of the hepadnaviruses. Hepatitis B surface antigen (HBsAg) is located in the lipid envelope of this small DNA virus. During the replicative phase of the virus, this surface antigen is produced in excess and is detectable in the blood of the infected. The incubation period of HBV is 6 weeks to 6 months.
Hepatitis C Virus (HCV) is a small, enveloped, positive-sense, single-stranded RNA virus. HCV is now known to be the major cause of parenterally transmitted non-A, non-B hepatitis. Antibodies to HCV are found in over 80% of patients with well-documented non-A, non-B hepatitis. Conventional methods fail to isolate the virus in cell culture or visualize it by electron microscope. Cloning the viral genome has made it possible to develop serologic assays that use recombinant antigens. Compared to first generation HCV EIAs using single recombinant antigens, new serologic tests include multiple antigens using recombinant protein and/or synthetic peptides to avoid nonspecific cross-reactivity and to increase sensitivity.
HIV is the etiologic agent of Acquired Immune Deficiency Syndrome (AIDS). The virion is surrounded by a lipid envelope that is derived from host cell membrane. Several viral glycoproteins are on the envelope. Each virus contains two copies of positive-sense genomic RNAs. HIV-1 has been isolated from patients with AIDS and AIDS-related complex, and from healthy people with high potential risk for developing AIDS. HIV-2 has been isolated from West African AIDS patients and from seropositive asymptomatic individuals. Both HIV-1 and HIV-2 elicit immune response. Detection of HIV antibodies in serum, plasma or whole blood is the most efficient and common way to determine whether an individual has been exposed to HIV and to screen blood and blood products for HIV. Despite differences in their biological characters, serological activities and genome sequences, HIV-1 and HIV-2 show strong antigenic cross-reactivity. Most HIV-2 positive sera can be identified by using HIV-1 based serological tests.
Treponema Pallidum (TP), a spirochete bacterium with an outer envelope and a cytoplasmic membrane, is the causative agent of the venereal disease syphilis. Although syphilis rates are declining in the United States after an epidemic between 1986 and 1990, the incidence of syphilis in Europe has increased since 1992, especially in the countries of the Russia Federation, where peaks of 263 cases per 100,000 have been reported. In addition, the positive rate of serological test results for syphilis in HIV-infected individuals has been rising recently. The serological detection of specific antibodies to TP has been long recognized in the diagnosis of syphilis since the natural course of the infection is characterized by periods without clinical manifestations. The antibody response to TP can be detected within 4 to 7 days after the syphilis chancre appears, allowing early detection and diagnosis of syphilis infection. A variety of antigens have been used in syphilis serological tests, such as Rapid Plasma Cardiolipin (RPR) or VDRL antigen, TP extracts derived from in vitro culture or inoculated rabbit testes. However, RPR and VDRL antigens are not treponemal specific, and whole TP extracts are not reproducible and contain a certain amount of contaminating materials such as flagella, which may lead to a nonspecific reaction in assays of test serum.
• Rapid test cassette
• Buffer
• Disposable dropper
• Package insert
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.
1.Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. For best results, the assay should beperformed within one hour.
2.Using the provided disposable dropper, transfer 2 drops of serum/plasma to each specimen well (S) of the cassette, then start the timer.
OR
Transfer 1 drop of whole blood specimen to each specimen well (S) of the cassette with the provided disposable dropper, then add 1 drop of buffer and start the timer.
OR
Allow 2 hanging drops of fingerstick whole blood specimen to fall into the center of each specimen well (S) on the cassette, then add 1 drop of buffer and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the membrane.
3. Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
