【Sample requirements】


1. Serum, plasma, and whole blood samples can be used for testing.
2. Serum / plasma sample collection: Serum and plasma should be separated as soon as possible after blood collection to avoid hemolysis. The separated serum and plasma should be tested quickly. If they cannot be used in a timely manner, they should be stored at 2- 8℃. After 3 days, they should be stored frozen at -20℃. Please make the sample recover to room temperature before testing. It is not recommended to use severe hemolytic and heat extinguishing samples.
3. Whole blood collection: use an anticoagulation tube to collect blood, or add an anticoagulant in the blood collection tube (heparin, EDTA salt, sodium citrate lamp anticoagulant are recommended), add the collected blood sample and shake it for later use. If it cannot be tested immediately, it can be stored at 2-8℃ for 7 days. Intravenous samples over 7 days are not suitable for this kt.

【Test procedure】

1.Start NIR-1000 dry fluoroimmunoassay analyser according to the instruction manual of the instrument, and carry out quality control verification according to the instruction manual of the instrument(Note: the reagent has been calibrated in advance, and the calibration curve parameters of each batch of reagent have been stored in the information card. The information card is inserted before use, so it is not necessary to calibrate again, and the test can be carried out only after the quality control is passed. Otherwise, the cause should be found out before testing.)

2.Transfer 20 μL of whole blood or 10 μL of serum or plasma specimen to the sample well, followed by adding 4 drops (100 μL)of sample diluent to the sample well.

3.Insert the test card into NIR-1000 dry fluoroimmunoassay analyser, read and record the results at 15 minutes after addition of samples, then dispose of used test appropriately.

 

HOW TO PERFORM THE TEST?

1. Remove a Test Device from the foil pouch by tearing at the notch and place it on a level surface.

2. Holding Extraction Reagent bottle vertically, add 10 drops (400μL) to the Extraction tube.

3. Insert the nasopharyngeal (and oropharyngeal) swab sample(s) into the extraction solution, then, mix the swab 10 times.

4. Remove the swabs while pressing against the solution tube in order to extract most of the specimen

5. Place the dropper cap and drop 3 drops (60~70μl) into the sample well.

6. Read the result in 10-15 minutes. Do not read results after more than 20 minutes.

 

Something you need to learn about:
1) What is the difference between an antigen test and a molecular test?
An antigen test detects specific proteins on the surface of the virus. These tests are quicker and less expensive, but have a higher chance of missing an active infection, according to the FDA.
A molecular (PCR or polymerase chain reaction) test detects the virus’s genetic material. These tests require a more complex technology to get results, and it usually takes a day or two to get those results (depending on lab capacity, results may take up to a week).
If an antigen test shows a negative result and you have reason to believe you may have the virus (because of symptoms or exposure), your doctor may order a molecular test to confirm the results.

2) Which tests are more accurate?
No test is 100% accurate, but the molecular tests are considered to be more accurate than the antigen tests, according to available research.
According to the FDA, an antigen test cannot “definitively rule out active coronavirus infection,” but positive results are “highly accurate” (negative results may require a confirmation test).
Harvard Medical School wrote in August that the reported rate of false negatives with molecular testing is as low as 2% and as high as 37%. A molecular test using a deep nasal swab will have fewer false negative results than samples from throat swabs or saliva, they say.
For antigen testing, Harvard noted that the reported rate of false negative results can be as high as 50%, but that the FDA has granted emergency use authorization for a more accurate antigen test.
In general, some of the issues that may affect the accuracy of a test include ineffective swabbing, contamination or mishandling of the sample, or problems with the testing chemicals, according to the FDA.

3) If antigen tests are less accurate, why would we use them?
Experts say the value in the rapid antigen tests is in the frequency of the testing rather than the accuracy, with repeated testing recommended. According to Science, getting a false negative in an antigen test two or three times in a row is rare. This strategy lines up with the NPR report mentioned above, which would employ daily testing of those in high-risk areas.

 

4) Who must be tested for COVID-19?
As per the Minister’s Directive: COVID-19: Long-Term Care Home Surveillance Testing and Access to Homes (Minister’s Directive) effective January 8, 2021, all staff, student placement and volunteers working in long-term care homes must be tested regularly in accordance with the Minister’s Directive, unless the exception for individuals who have previously had laboratory confirmed COVID-19 applies. The testing requirements in the Minister’s Directive include all individuals working in long-term care homes who are: • Staff as defined in the Long-Term Care Homes Act, 2007 • Volunteers as defined in the Long-Term Care Homes Act, 2007 • Student placement, meaning any person working in the long-term care home as part of a clinical placement requirement of an educational program of a college or university, and who does not meet the definition of “staff” or “volunteer” under the Long-Term Care Homes Act, 2007. The Minister’s Directive also includes additional testing and documentation requirements for general visitors, caregivers and support workers.
