Quick test Covid 19: Particularities of use

The main characteristics of this rapid test compared to other similar tests are the following:

Rapid test Covid19 for detection of IgG / IgM.

  1. It is a qualitative membrane-based immunoassay for the detection of antibodies.
  2. This test has two components. One is the IgG component and the other is called IgM. In the IgG component, the anti-human IgG is coated in the region of the IgG test line. The test contains anti-human IgM and anti-human IgG as capture reagent, antigen 2019-nCoV as a detection reagent. IgG reagent is used in the control line system.
  1. Testing should be done immediately after samples have been collected. They should not be left at room temperature for long periods and if they do freeze. They should be completely thawed in order to work with them. Except in the case of whole blood samples collected by fingerstick. In this case it must be analyzed immediately.
  2. The test contains the following: test cassettes, droppers, a datasheet, and a buffer. Before using them, they must be allowed to reach room temperature.
  3. The test procedure and the interpretation of the test result should be followed closely. Especially when the presence of specific antibodies to the SARSCoV-2 virus is checked in the serum, plasma or whole blood sample.
  4. The test results will only indicate the presence of IgG and IgM antibodies against SARS-CoV-2 in the person. It should not be used as the sole criterion for the diagnosis of SARS-CoV-2 infections.
  5. The hematocrit level of the blood can affect the results of this test. The hematocrit level must be between 25% and 65% for the results to be accurate.
  6. Negative results in this test do not rule out SARS-CoV-2 infection. Especially when they are performed on people who have been in contact with the virus. In this case, a follow-up test, with a molecular diagnosis, must be carried out to rule out an infection in these people.


So, if you are looking for a test to adequately respond to the demands of tests for Cooronavirus, get the rapid test Covid19 for detection of IgG / IgM. You will win!

Viral DNA-RNA Purification Kit

The DNA and Viral RNA Purification Kit is a Real brand product to make laboratory work faster. It is a set of elements that is designed for rapid and simultaneous purification of viral DNA and RNA from cell-free samples such as serum, plasma and cerebrospinal fluid.

A simple and very effective system with which we can carry out our work safely and quickly and can meet the current high demand for analysis of all kinds by the general population. Its effectiveness has been highly certified, so it is part of the product catalog that Durviz, as the official distributor of the brand, and we put it at your fingertips.


Goals of the purification kit

The Real brand Sample Purification Kit, available from Durviz, works to meet the objectives it intends to cover. In this respect, it should be borne in mind that viruses, when lysed with detergent and proteinase K, release total viral nucleic acids.

Therefore, in the presence of a caotropic salt, viral nucleic acids selectively bind to the fiberglass membrane in a special centrifuge tube. A process in which nucleic acids remain united while a series of rapid wash and spin steps remove contaminating cellular components.

Finally, low-salt elution removes viral nucleic acids from the fiberglass membrane. Enough to have the sample ready for analysis.

An important part of the work with this kit is that the process does not require nucleic acid precipitation, organic solvent extractions, or extensive handling of nucleic acids. This is a big difference from other similar products we can find on the market. That’s why your results are better and labs are purchasing this kit for their daily work.

The Real Spin Viral Kit for DNA and RNA analysis can be used for viral RNA and DNA isolation from a wide range of viruses that affect them.

However, according to the manufacturer, performance cannot be guaranteed for all virus species and must be validated by the customer. Therefore, we advise you to consult with us before you buy any questions you may have. We will give you all the details you need.

Real Saliva Viral. Saliva samples.

Real Saliva Viral: Brochure

Real viral saliva is a simple and practical kit that aims to bring speed and practicality to laboratory work. This novel product provides a safe and fast procedure for collecting, stabilizing and transporting saliva samples. Something fundamental especially now that large amounts of testing are being carried out by COVID 19. A procedure in which it has proven to be highly effective, allowing a large amount of sample collection to be made without any of them being harmed.

An all-in-one that allows us to work with 1 ml saliva samples at room temperature, allowing viral DNA/RNA to be stabilized without any problem. To do this, this product uses its own solution (contained in the kit itself) that inactivates viruses and prevents the degradation of nucleic acid in samples collected with our system. In this way, non-infectious samples are properly preserved for safe handling and sent.

The saliva samples we treat with this Real Saliva viral substance are kept at room temperature for a long period of time. Thus, in the case of DNA we have to talk about a period that extends over an entire year; and in the case of one-stage RNA that goes up to a month).

However, this is not the only advantage in or that of conservation. Saliva samples can also be frozen (-20/-80°C) for extended periods. A larger stage than other saliva testing kit offers.


Operation of a Real Saliva Viral

The way we can use this kit is very simple and is summarized in the following steps:

  1. Before removing the sample, people should be warned not to eat, drink, smoke or chew gum. Unless they haven’t done so 30 minutes before the sample was collected. Otherwise, it will be very difficult to get 1 ml of saliva. An extraction that can take several minutes in normal situations and that in the cases referred extends over time.
  2. The funnel must be inserted into the sample collection tube. It is advisable to rub the cheeks with the tongue and teeth for stimulation of saliva secretion.
  3. Collect saliva until 1 ml line level is reached.
  4. Remove and discard the funnel.
  5. Remove the cap from the saliva preservation solution and add all its contents to the collection tube.
  6. Close the sample collection tube with its green cap.
  7. Shake the tube vigorously for 15 seconds to mix saliva well with saliva preservation solution. At this point we must avoid unsolving saliva lumps.
  8. The saliva sample is already preserved and ready for storage, shipping and processing.
