INDICAID^® COVID-19 Rapid Antigen Test FAQ

An antigen is a molecule or molecular structure outside of a pathogen that, can trigger an immune response when detected in the human body. Common antigens include simple intermediate metabolites such as carbohydrates, fats, hormones, and larger molecules including polysaccharides, phospholipids, nucleic acids and proteins.

Antigens are present in SARS-CoV-2 viruses, which can be often be found in the respiratory tract during early-stage infections. These antigens, when detected, serve as markers for disease exposure. 

INDICAID^® is an effective COVID-19 Rapid testing tool kit with the following advantages:
1) High sensitivity: As of January 11th, 9236 sampling verifications are conducted in the Community Testing Scheme set by the Hong Kong Government, resulting in more than 93% sensitivity, which is the only product in the world that passes almost 10,000 clinical sampling tests. Compared to INDICAID^®’s competitors, the product can detect antigens from lower viral load samples. The high detection rate greatly reduces the false-negative rate.
2) Easy-to-use: Results will be ready in three steps.
3) Fast: While the traditional PCR tests results require at least a day to come out, INDICAID^® only requires 20 minutes.
4) Convenient: No requirements for professional training and equipment, can be used anywhere, anytime, by anyone.
5) Developed and manufactured in Hong Kong: Guarantee better technology and higher product quality.

INDICAID^® is suitable for everyone to use where the test can be conducted anywhere anytime conveniently, thus ensuring a COVID-free environment. This product is particularly suitable for the following group:
 1) People with COVID-19 symptoms Such as fever or respiratory tract symptoms etc.
2) People with relevant epidemiological or contact history
     a) Recent contact with patients COVID-19 or suspected patients
     b) Recently travelled to communities, shopping malls or other places related to COVID-19.
3) People who frequently travel to places with high population density.
     a) Frequently use public mass transportation
     b) Work in large companies
     c) Attend mass events, visit communities and places with high population density
4) High-risk populations such as elderly and people with comprehensive syndromes.

INDICAID^® detects the antigen within the virus, which takes 2-3 days after infection in most cases. Test early can effectively proceed quarantine and offer suitable medical treatment.

INDICAID^® uses nasal swab sample, which will sample directly in nostrils.

The INDICAID^® sampling process is simple; it only requires putting the sampling swab into the nostrils around 1 inch (2.5 cm) deep. Therefore, it will not bring any discomfort or pain.

INDICAID^®’s operations are very simple, put the swab provided in the product into the nostrils for sampling, mix it with the buffer solution, drip into the test device, and the results will be ready in 20 minutes.

For antigen testing products, there are two indicators for accuracy. First, sensitivity indicates the proportion of detected positive cases. Generally, the higher the sensitivity, the positive agreement rate is high while the false-negative rate is low.
Second, specificity indicates the proportion of detected negative cases. Generally, the higher the sensitivity, the negative agreement rate is high while the false-positive rate is low.
The sensitivity and specificity of INDICAID^® COVID-19 Rapid Antigen Test are 93% and 99% respectively.

INDICAID^® has passed extensive clinical verification.
 - Conducted in the United States and compared with traditional PCR test, the sensitivity and specificity of INDICAID^® reach 96% and 99% respectively.
- In Hong Kong Government’s Community Testing Scheme, INDICAID^® is used in dual-track testing and has completed 9236 sampling tests, which is the world's largest clinically verified product. Overall speaking, the sensitivity and specificity of INDICAID^®are 93% and 99% respectively.

Compared to traditional PCR test, periodic and regular testing can better the spread of the Coronavirus. The recommended schedule is as follow:
 - For low-risk populations, such as healthy and young people and have little contact with the crowd, it is recommended to test once per week.
- For moderate-risk populations, such as workers in mid-scale companies, it is recommended to test twice per week.
- For high-risk populations, such as people who work in a dense and crowded environment, elderly, it is recommended to test daily.

No. The test can be conducted anytime.

If you tested positive with INDICAID^®, please call PHASE Scientific customer hotline 9014 6321 for further consultation.

INDICAID^® is developed and manufactured in Hong Kong with strict monitoring in different technical indicators and the production line.

COVID-19 is mainly airborne, which will first pass through the nasal cavity and enter the upper respiratory tract. Many medical researches and testings prove that there is relatively high virus content in nasal swab samples and, in fact, using nasal swab for sampling is one of the common practices internationally. Compared to other testing methods, the nasal swab sampling method in INDICAID^® can guarantee higher testing sensitivity.

1) Higher sensitivity, the only product in the world that passes almost 10,000 clinical sampling tests with 93% sensitivity.
2) Using nasal swab for sampling will have accurate results and will not cause any pain and discomfort.
3) Manufactured in Hong Kong, guarantee in high quality.
4) Retail price is only HKD$120, which is affordable.
5) If you tested positive with INDICAID^®, you can get a free traditional PCR test in a medical lab that is certified by the Hong Kong Government.
