Rapid coVID-19 and Influenza A+B antigen test

The COVID-19 and Influenza A+B antigen rapid test is a rapid immunoassay for the qualitative detection of antigens to the SARS-CoV-2, Influenza A and Influenza B virus. For its operation, it uses nasopharyngeal swab samples from individuals suspected of being affected by SARS-CoV-2. Or they have an influenza infection along with the clinical presentation and results of other laboratory tests.


Samples for rapid detection of COVID 19 and Influenza

For the detection of COVID-19, an antigen is usually found in upper airway samples during the acute phase of infection. Positive results indicate the presence of viral antigens in the person. But, be careful, a clinical correlation with the patient’s history and other diagnostic information is necessary to determine the status of the infection.

Positive results that may be obtained do not rule out bacterial infection or co-infection with other viruses. And it is possible that the agent detected is not the definitive cause of the disease.

On the other hand, negative results in such an analysis do not exclude SARS-CoV-2 or Influenza A B infection and should not be used as the basis for the diagnosis of treatment or for making management decisions.

Therefore, it is always recommended that negative results be treated as presumptive and confirmed with a molecular assay.

COVID 19 Combined Quick Test

The COVID-19 and Influenza A+B rapid antigen test in combination is designed for use by staff working in a trained clinical laboratory.

This test is a qualitative membrane-based immunoassay for the detection of SARS-CoV-2 antigens in a human nasopharyngeal swab sample. To do this, the antibody SARS-CoV-2 is coated in the test line regionDuring the COVID-19 rapid antigen test, the sample reacts with particles coated with antibodies to SARS-CoV-2 that have been placed. This causes the mixture to migrate up on the membrane by capillary action and react with the SARS-CoV-2 antibody in the test line.

Quality controls the rapid test of COVID-19 antigen and Influenza A+B

If the sample contains SARS-CoV-2 antigens, a color line appears in the test line region. If the sample does not contain antigens, no color line appears.

To serve as a control, a colored line will always appear in the control region, indicating that the appropriate sample volume has been added. And of course, the membrane absorption has occurred.

In this test, antibodies specific to influenza A and influenza B nucleoproteins are coated separately in the test line.

During the test, the specimen removed to the person reacts with influenza A and/or B antibodies covering the particles. The mixture migrates to the membrane to react with influenza A and/or B antibodies and to generate one or two colored lines in the test regions.

The presence of this color line in one or both of the test regions indicates a positive result. To control the procedure, we will always have a colored line in the control region if the test was successful.

At Durviz we know how important it is to have tests of this kind in your laboratory. That’s why we put it at your fingertips on our website. So if you want to buy them, you should contact us.

Real Saliva Viral

REAL Saliva Viral Collection Kit

Real viral is the name of a kit that provides a safe and fast procedure with which to collect, stabilize and transport saliva samples from 1 milliliter at room temperature. A procedure that stabilizes viral DNA/RNA in order to study it. This makes new and high-quality ways available to scientists to detect the presence of COVID 19 in people.

The main advantage of Real Viral is that it inactivates viruses and prevents the degradation of nucleic acid in samples collected with our system, resulting in non-infectious samples to be handled and sent safely.

Samples obtained by this procedure are kept at room temperature for one year for DNA and one month for RNA. In addition, they can be frozen (-20/ -80° C) for extended periods.

The kit contains the following:

  • 100 doses of 1 milliliter of the Real viral solution
  • 100 units of funnels
  • 100 saliva collection tubes

All of them are distributed at room temperature.


Features of the Real Saliva viral

The main features of this kit are:

  •  Used for the collection, storage and transport of viral samples of 1 ml of saliva.
  • Microorganisms and viruses are inactivated to make their transport and handling safe and easy.
  • This system can be used to isolate human genomic DNA or viral DNA/RNA, any of the procedures we need to perform.
  • Allows transport to be carried out at room temperature without affecting the sample.
  • Preserve total DNA, including viral DNA, at room temperature (4º-25ºC) for one year.
  • Preserve total RNA, including viral RNA, at room temperature (4º-25ºC)1 month.
  • It is a system compatible with most of the DNA and RNA isolation methods on the market.

For greater efficiency, from Durviz we recommend using our REAL Kits as a complement.

Use of Real Saliva Viral

To make proper use of this sample kit, follow the instructions below:

  1. Do not eat, drink, smoke or chew gum at least 30 minutes before collecting the sample. This way we make sure that the saliva is not contaminated. It should be remembered that to get 1 ml of saliva it can take several minutes.
  2. Insert the funnel into the sample collection tube. Then rub your cheeks with your tongue and teeth to stimulate saliva secretion.
  3. Collect saliva until it reaches the level of the 1 ml line of the tube. It is important to remove excess bubbles by hitting on a hard surface.  They should not be taken into account in the measurement.
  4. Remove and discard the funnel.
  5. Remove the cap from the saliva preservation solution and add all its contents in the collection tube with 1 ml of saliva.
  6. Close the sample collection tube with its green cap.
  7. Shake the tube vigorously for 15 seconds to mix saliva well with the saliva preservation solution. Prevent unsolving saliva lumps.
  8. The saliva sample is now preserved and ready for storage, shipping and processing.
