Rapid COVID 19 test from blood, serum or plasma

If you need to do a rapid COVID 19 detection test from blood, serum or plasma samples, at Durviz we have the product you need. It is an exclusive proposal for use in laboratories

 

Rapid COVID 19 test from blood, serum or plasma

The rapid test that we propose at Durviz is a lateral flow chromatographic immunoassay that allows the qualitative detection of IgG and IgM antibodies against 2019-nCoV. An action that it is capable of carrying out in human blood, serum, plasma or also in a blood sample with a lancet.

This product uses immunochromatography as a detection technique. These types of tests are commonly used for medical diagnosis both for home tests and for use in the laboratory. Hence, it is one of the most requested media by professionals at the present time.

And it is that immunochromatography is one of the most widely used immunodiagnostic techniques today. Its main attractions are: the simplicity and speed of the tests that use this proposal. Hence, with the current need for diagnoses due to the COVID 19 pandemic, there are more and more applications of this technique in the field of tests. Especially since it does not need reagents or additional instrumentation for its operation. Something that does occur in other similar methodologies that are applied to the clinical field.

 

Advantages of the rapid COVID 19 test

The main advantages of this product are the following:

  • It is presented in a strip format, in which the test sample flows along a solid substrate through capillary action.
  • This is a combined antibody test that can provide information on the stage of infection of the person being tested. And it is that the detection of COVID-19 IgM antibodies tends to indicate a recent exposure to COVID-19, while the detection of COVID-19 IgG antibodies indicate a later stage of infection.
  • The test contains anti-human IgM and anti-human IgG as capture reagent, 2019-nCoV antigen as detection reagent. An IgG reagent is used in the control line system.
  • It is a product for exclusive use in laboratories.

 

To all this must be added, in addition, that IgM provides the first line of defense during viral infections, followed by the generation of adaptive responses of high anity of IgG for long-term immunity and immunological memory.

 

COVID 19 Rapid Test Features

The main features of the COVID 19 rapid test are as follows:

  • Testing should be done immediately after samples have been collected.
  • Serum and plasma samples can be stored at 2-8 ° C for up to 7 days. For long-term storage, serum / plasma samples should be kept below -20 ° C. Whole blood collected by venipuncture should be stored at 2-8 ° C if testing will be performed within 2 days of collection.
  • Negative results do not rule out SARS-CoV-2 infection. This should be taken into account particularly in those people who have been in contact with the virus. A follow-up test with a molecular diagnosis should be considered to rule out infection in these individuals.
  • Results of antibody tests should not be used as the sole basis for making a diagnosis. Neither to exclude a SARS-CoV-2 infection or to report infection status.

 

So, if you are looking for a system that allows you to perform a rapid test to detect the presence of COVId 19 from blood, serum or plasma, do not hesitate and visit our website. You can buy both this product that we have reviewed in this article, as well as many other accessories. Everything so that you can acquire the best and most reliable results in your laboratory.

Covid-19 quick test for IgG/IgM detection

You can now find covid-19 quick test for IgG/IgM detection in Durviz. An immuno lateral flow chromatographic assay for the qualitative detection of IgG and IgM antibodies against 2019-nCoV in human blood, serum, plasma or also in a lancet blood sample. This puts at our fingertips an effective method for rapid diagnosis of COVID-19 infection in the person undergoing the test.

And all this doing a comprehensive analysis of the composition of the elements in the blood. So the detection of COVID-19 IgM antibodies tends to indicate recent exposure to COVID-19, while detection of COVID-19 IgG antibodies indicate a later stage of infection. Information needed to perform epidemiological studies, as well as the degree of involvement the disease had on the person.
And it is widely accepted that IgM provides the first line of defense during viral infections, followed by the generation of IgG’s high-anity adaptive responses for long-term immunity and immune memory.

Covid-19 quick test: IgM efficiency

Immunochromatography is one of the most relevant immunodiagnostic techniques out there. Its main advantages are: the simplicity and speed of the test.
Y is that more and more applications are being made of this technique, both in the field of tests, because no reagents or additional instrumentation are necessary; and in the clinical field.
This action can be performed using a simple device developed to detect the presence (or absence) of a target compound in the sample (the matrix). Element that makes up this test. It consists of two components: an IgG and an IgM, which allow to detect the presence of IgG and IgM antibodies independently.
Its operation is simple and very effective since the region of the IgG detection line is coated by human anti-IgG, and when depositing the sample in the analysis area, the possible IgG anti 2019-nCoV present, react with colored particles coated with antigens of 2019-nCoV present in the cassette. The mixture migrates through the membrane by capillary and reacts with human anti-IgG antibodies in the test region reserved for IgG detection. If the sample contains IgG antibodies for 2019-nCoV, a colored line appears in the designated region of IgG as a result of this antigen-antibody bonding reaction.
Similarly, in the IgM detection line, human anti-IgM antibodies are attached, in the case of a positive sample for IgM from 2019-nCoV, the complex formed together with the 2019-nCoV antigens reacts with the anti-IgM antibodies and a colored line appears in the corresponding region.
If the sample contains neither IgG nor IgM, no lines will appear in the test areas for IgG or IgM, indicating a negative result. However, as a check to ensure that the sample volume used is sufficient and that the procedure has been successful, a third line appears in the control area.  
These types of tests are used for medical diagnosis and home testing, as well as in the lab.

A reliable and quality test

Given the importance of results in people’s lives and in the safety of their environments, special attention has been paid to test controls.
In fact, internal controls are included in the test. This is displayed on a colored line appearing in the control region (C) composing the internal control of the procedure. This ensures that the technique carried out is correct and that the sample volume used is sufficient. Control standards are not included in the kit, however, it is recommended to test with negative and positive controls as indicated by good laboratory practices to verify the test result.

If you are looking for a test with which you can make reliable diagnoses about diseases as serious as the one that currently affects us by COVID-19, do not hesitate and get the kit that we have in Durviz.

Se trata de una manera inmejorable de poner a la gente en conocimiento de su estado de salud o pueda detectar la presencia de este coronavirus y tomar las medidas pertinentes.

LiliF COVID-19 Kit RT-PCR (detection of genes RdRP, E, N, RNaseP) CE IVD developed by  INTRON

It should be noted that there are currently four genes in the Coronavirus family. They are known as alpha, beta, gamma and delta. Alpha and beta corona viruses can cause disease in both humans and animals, while others, such as gamma and delta coronaviruses, only infect animals.

The new coronavirus (COVID-19) belongs to those we have previously identified as beta genes. It is one of the new infectious coronaviruses that, upon contact with the human body, infects them as a pathogen of massive pneumonia that occurred in The town of Wuhan, hubei Province, China, in December 2019.

Given the severity of this disease, it is very important to diagnose the infection quickly, as there are no vaccines or antivirals approved for prophylactic or therapeutic purposes.

The kit RT-PCR  we offer in Durviz allows to detect, in real time, the new coronavirus using the RT-PCR probe method, through the reaction of the specific primer and the fluorescent probe in the sample.

RT-PCR can detect the RdRp gene and the E gene, markers for the detection of new coronaviruses, which is an important help for researchers. In addition, the N gene suggested by the U.S. CDC, and the RNaseP gene, which confirms the validity of all test reactions, are included.

With all this, the intended use of this test makes it possible to detect the presence of viruses in sputum samples in the lower airways, bronchoalveolar washing fluid, nasopharyngeal smears and oropharyngeal smears collected simultaneously in the upper airways.
