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.
REAL Centrifuge Model

Centrifuges for concentration techniques

If you are looking for a device with which you can perform concentrations in your laboratory, and by extension to be able to formulate adequate diagnoses with little margin of error, the concentration centrifuges of the Real brand, will surprise you pleasantly.

These are two models of centrifuges (BDT4 and BDT4-2) that will allow you to perform numerous actions with which you will gain time and effort in the daily tasks of your laboratory.
To get to know them in depth, in Durviz we have written this article with which we want to help you choose the model that suits you best.

Models of concentration centrifuges

Centrifugal to develop different concentration techniques are devices that allow you to perform laboratory tests in a short time and with high reliability.

The BTD4 model is a small concentration centrifuge, specially designed for human diagnostics.  It is portable and its operation is very simple. It is a tube-compatible device of up to 20 ml of the Real brand and reaches a speed of 4000 revolutions per minute.  Includes an 8-vial angular rotor of the same brand.

Works thanks to a maintenance-free induction motor.  In addition, this engine is suspended on rubber parts that reduces vibrations that may occur during operation.

The BTD4-2 model is a concentration centrifuge designed for routine medical analysis of hospitals. It is a model that has a wide variety of accessories, which make them also compatible with the analysis work that is carried out in research processes.
Is a centrifuge compatible with tubes with capacity up to 50 milliliters. Like the other model of the brand, this device also reaches a speed of 4000 revolutions per minute.

It has a 50 milliliter Real Midi sistem six-pipe angular rotor, or for an oscillating rotor of up to 8 15 milliliter Real Midi System tubes.  Sus main physical characteristics are as follows:
  • It has an exterior metal structure.
  •  It has a series of rubber supports that reduce vibrations that can arise when in operation.
  •  It has a series of gas springs to prevent the door from falling.
  • You have an emergency release of the lid lock.
  •  It has a safety lock on the lid to prevent it from opening during centrifugation.
  •  Its operation is extraordinarily quiet.
  • It has a countdown timer that marks the times of each process.
  •  Allows the recovery of the data of the last set parameters.
  • Performs a self-diagnosis of errors in case they appear.

Both concentration centrifuges are compatible with the Real brand Mini and Midi Sistem systems.

All these products allow to make a higher performance to the systems of obtaining, preserving and analyzing all kinds of human or animal samples. Especially those related to the tests of intestinal parasites from faecal samples, but not exclusively to them.

At Durviz Laboratories we put them at your fingertips so you can enjoy the features of both models.

To buy them you only have to enter our website and purchase them, once you have registered as a customer. We will take care of sending them to your home or the home you indicate, with all the guarantees and care that each product requires. And always at the best price. Remember, in this sense, that we are official and authorized distributors of the main brands manufacturers of laboratory products. Something that reinforces the way we work and that encourages us to continue to grow in the sector, where we already occupy a prominent place.
