Advantages of Cancer Antigen Rapid Test Cassette

Speedy Results: Rapid antigen tests provide results in a matter of minutes, enabling prompt identification of infected individuals. This rapid turnaround time is invaluable in swiftly isolating cases and preventing further transmission within communities.
Ease of Use: Unlike some other diagnostic methods, rapid antigen tests are simple to administer and do not require specialised equipment or trained medical professionals. They can be conducted in various settings, from healthcare facilities to workplaces and even at home, facilitating widespread testing efforts.
Early Detection: Early detection is key to controlling outbreaks. Rapid antigen tests are effective in detecting the virus during the early stages of infection, even before symptoms appear. This early identification allows for timely intervention, reducing the risk of widespread transmission.
Cost-Effectiveness: Rapid antigen test kits are generally more affordable compared to other diagnostic methods, making them accessible to a broader segment of the population. Their affordability promotes regular testing, especially in high-risk environments, contributing to proactive disease management.
Screening Tool: Rapid antigen tests serve as valuable screening tools for large scale testing initiatives, such as screening travellers at airports or screening employees before entering workplaces. By quickly identifying asymptomatic carriers, these tests help prevent outbreaks in vulnerable settings.
Complementary to PCR Testing: While polymerase chain reaction (PCR) tests remain the gold standard for diagnosing infectious diseases, rapid antigen tests complement PCR testing efforts. They can be used for initial screening or to confirm suspected cases, conserving PCR resources for confirmatory testing when needed.

Convinient Procedure
Allow test cassette, specimen, and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it as soon as possible. Best results will be obtained if the assay is performed within one hour.
Place the cassette on a clean and level surface. For Serum, Plasma or Venipuncture Whole Blood specimen:
• Hold the dropper vertically and transfer 1 drop of serum or plasma (approximately 40µl) or 2 drops of venipuncture whole blood (approximately 80 µl)) to the specimen well (S) of thecassette, then add 1 drop of buffer (approximately 40µl) and start the timer.See illustration below.
For Fingerstick Whole Blood specimen:
• To use a capillary tube: Fill the capillary tube and transfer approximately 80 µl of fingerstick whole blood specimen to the specimen area of test cassette, then add 1 drop of buffer (approximately 40µl) and start the timer. See illustration below.
Wait for the colored line(s) to appear .Read results at 10 minutes. Do not interrupt the result after 20minutes.
