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, serum or plasma.
The acronym TORCH was introduced in 1971 by Nahmias et al. to highlight a group of viral diseases which affect thefoetus and newborn, namely Toxoplasma gondi, rubella virus, cytomegalovirus (CMV), and herpes simplex virus (HSV)These diseases often lead to a similar clinical picture which include one or more of the following clinical signs: ow birthweight, prematurity, purpura, jaundice, anemia , microcephaly, hydrocephaly, cerebral calcification, chorioretinitis, cataracts.microphthalmia , and pneumonitis. TORCH screening is now widely requested by clinicians investigating infants andpregnant women for congenital, perinatal and neonatal infections.
• 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 device 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 device and start the timer.
OR
Transfer 1 drop of whole blood specimen to the specimen well (S) of the device 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
