Torch rapid test combo is a rapid qualitative lateral flow test designed for the qualitative detection of the IgG antibodies to thefollowing viruses: Toxoplasma gondii (Toxoplasmosis)(TOXO), Cytomegalovirus(CMV), Rubella Virus (RV), Herpes Simplex Virus Type 1 (HSV-1) and Herpes Simplex Virus Type 2 (HSV-2) in human whole blood, srum or plasma.
The ToRCH IgG/IgM Antibodies Combo Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Toxo, Rubella, CMV, and HSV1/2 in Serum or Plasma. Each test consists of: 1) a burgundy colored conjugate pad containing TORCH recombinant envelope antigens conjugated with Colloid gold (TORCH conjugates) and rabbit IgG-gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with the antibody for the detection of IgM anti-TORCH, T2 band is coated with antibody for the detection of IgG anti-TORCH, and the C band is pre-coated with goat anti rabbit IgG.
When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-TORCH, if present in the specimen, will bind to the TORCH conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a TORCH IgG positive test result and suggesting a recent or repeat infection. IgM anti-TORCH if present in the specimen will bind to the TORCH conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a TORCH IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another test cassette.
• Rapid Test.
• Buffer
• Disposable pipettes
• Instruction for use.
- The kit should be stored at 2-30°C until the expiry date printed on the sealed pouch.
- The test must remain in the sealed pouch until use.
- Keep away from direct sunlight, moisture and heat.
- Do not freeze.
- Care should be taken to protect the components of the kit from contamination. Do not use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipment, containers or reagents can lead to false results.
Sample Collection&Storage
• The Torch Test is intended for use with human whole blood, serum or plasma specimens only.
• Only clear, non-hemolyzed specimens are recommended for use with this test. Serum or plasma should be separated as soon as possible to avoid hemolysis.
• Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8°C for up to 3 days. For long term storage, specimens should be kept below -20°C.
• Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.
• If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents.
• Icteric, lipemic, hemolysed, heat treated and contaminated sera may cause erroneous results.
Bring tests, specimens, buffer 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 cassette with patient or control identification. For best results, the assay should be performed within one hour.
2. Using the provided disposable pipette, transfer 2 drops of serum or plasma specimen to the specimen well (S) of the cassette and start the timer.
OR
Transfer 1 drop of whole blood specimen to the specimen well (S) of the cassette with the provided disposable pipette, 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 window.
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 within 10-15 minutes.
