This is a product that facilitates the collection and handling of samples with which to check the presence of this virus in people.
For this reason, we have written this article in which we explain what this rapid Covid 19 test that we offer you in Durviz is and how it works.

Covid 19 rapid test for healthcare professionals

The Covid19 rapid test for healthcare professionals is a lateral flow chromatographic immunoassay that allows the qualitative detection of IgG and IgM antibodies against 2019-nCoV. A rapid test that can be performed using human blood, serum, plasma. But, also in a lancet blood sample.
This rapid test uses a technique called immunochromatography. This is a very effective way that is used in medical diagnosis. Specially, with healthcare professionals in mind. People who need to speed up their work process. And who needs to minimize the margins of error in the tests they carry out.


Immunochromatography for diagnostics

Immunochromatography is one of the most widely used immunodiagnostic techniques in the current field. It is especially attractive for the following reasons: its simplicity and the speed it takes to carry out tests. In addition, it does not need reagents or additional instrumentation for its operation.

Something that does occur in others similar methodologies applied to the clinical field.
For this reason, it is one of the techniques most used in laboratories around the world. And it is a technique that helps to save time in obtaining data. And also, an effective treatment of the pandemic.

Advantages of the rapid test Covid 19

Durviz rapid test has a lot of advantages. If you compared to other similar products currently on the market, this is better. Some of these advantages are the following:
1. This is a product that is presented in a strip format. In it, the sample flows along a solid substrate through capillary action. After yo have the results. Very quickly, and without the need for any manipulation.
2. It is a combined antibody test. It can provide information on the stage of infection of the person being tested. Hence, this is that the detection of COVID-19 IgM antibodies tends to indicate a recent exposure to the COVID-19 virus. Then, while the detection of COVID-19 IgG antibodies indicate a later stage of infection. Which means having more information.
3. The test contains substances called anti-human IgM and anti-human IgG. This substance functions as a capture reagent, 2019-nCoV antigen, and as a detection reagent. Besides, IgG reagent is used in the control line system, to ensure that the device is working properly.
4. It is for exclusive use in laboratories.

Hence, if you want your professionals to work with high-quality products that provide optimal and reliable results, don’t hesitate and buy the Covid 19 rapid test for healthcare professionals from Durviz.

Detection of COVID19 in real time with LiliF COVID-19

Detection of COVID19 in real time is possible with LiliF COVID-19. A very fast and highly efficient test that allows us to detect the presence of COVID 19 in the person undergoing the test.


What is the LiliF COVID-19 test

The LiliF real-time COVId detection test is a test that uses an RT-PCR probe. This test can detect the new coronavirus using the real-time RT-PCR probe method, through the reaction of the specific primer and the fluorescent probe in the sample.

So far, it has been proven that this test can detect the RdRp gene and the E gene, which are markers for the detection of new coronaviruses. In addition, this test also includes the N gene suggested by the US CDC and the RNaseP gene.

Unlike other similar tests that we can find on the market, this kit provides the necessary components to perform the RT-PCR separately. And all this being able to use the consumable selected by the user and being compatible with any thermal cycler.

Remember that this kit contains everything you need, you should not mix it with any other product other than it.


Detection of COVID19 in real time with LiliF COVID-19

For its correct operation, sputum in the lower respiratory tract, bronchoalveolar lavage fluid (BAL) or nasopharyngeal smear (NS) and oropharyngeal smear (OS) collected simultaneously from the upper respiratory tract of the person to be analyzed is necessary.

The entire process must be done in a clean bench to ensure that there is no contamination that can affect the final result.

For this, the kit includes a swab that allows the collection of these samples.

Although its operation is simple, it is recommended that its manipulation be carried out only by specialized personnel. Including the toilet. Otherwise we could get some alteration of the result, due to bad handling. In addition, during its handling it is convenient that we protect ourselves with masks. This way we will avoid spraying when opening the lid.


COVID19 and other coronaviruses

At this point, it must be remembered that so far a total of four genders have been identified in the Coronavirus family. They are known as alpha, beta, gamma, and delta.

The alpha and beta corona viruses can cause disease in both humans and animals. While other types such as gamma and delta coronaviruses only infect animals.

The new coronavirus (popularly known as COVID-19) belongs to the beta. Hence, it is one of the new infectious coronaviruses that infects the human body as a pathogen of massive pneumonia that occurred in Wuhan, Hubei (China) in December 2019. And that has subsequently spread throughout the world, being considered a pandemic a few months after the first case was detected.

Therefore, it is very important to diagnose an infection quickly. Since, at the moment, their vaccines are not available to everyone or are in a trial period. And that its reliability is not one hundred percent; and even that its administration is carried out in two phases that have months of difference between both.

It should also be noted that there are no antivirals approved for prophylactic or therapeutic purposes.

However, the choice of these tests must be done appropriately. Well, there is a wide offer on the market, and it is necessary to know them before purchasing them. For this reason, at Durviz we have developed this product. A high-quality, simple test that contains everything we need to perform the test and that will surely help us to obtain a reliable result.

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.

Graham test safe & clean REAL for the detection of oxyide

Graham test safe and clean from REAL laboratory is the name of the first test on the market that we can purchase ready for use in our work environment.

Are test carriers that we can use in the laboratory, and they have been specially prepared for the detection of Enterobius vermicularis, a small parasitic nematode of humans popularly known as “oxyide”. A very common parasite that causes an intestinal disease known as oxyuriasis or enterobiasis. What is commonly referred to as the generic name of worms.
Although the infestation of this parasite is not serious, they are usually very annoying. Thus, the most common symptoms are severe pain and itching around the anus, especially during night rest, also assuming sleep disturbance and weight loss.

The itching that causes the presence of this parasite favors the reinfesstation of it. The eggs of the nail are introduced under the nails with the scratch, contaminating the hands and facilitating their intake by the person affected by this parasite. They can also spread through the air and be inhaled by people. Eggs ingested by hosts hatch in the duodenum and mature in the large intestine, where they are housed.


Real laboratory Graham test safe and clean employment

The laboratory is usually diagnosed with the presence of oxyides by recovering eggs from the perianal area of the affected. This is usually done by using the Graham Test and its subsequent microscopic identification. For samples to be useful, they must be collected for 3 consecutive days to be representative. But in all of this, what is the Graham Safe & Clean Test?

It is a system composed of three glass slides with adhesive tape, which are ready for use. All of them are included in a plastic box that protects them during transport from the lab to their final destination. It also includes a flexible and soft plastic material (cap) device that attaches to one end of the slide for easy sampling.

The main advantages of the Graham Safe & Clean Test are as follows:
• This is a clean and safe system.
• Simplifies sampling.
• Avoid direct contact with the glass.
• Protects against possible contagions so the reliability of the results is very high.
• Marked with the European Union’s IVD quality seal.

The use of this type of carrier is very simple and just follow the following steps:
1. The first thing is to place the cap on the unlabeled end.
2. Remove the adhesive tape from the glass and bring it to the glass cap.
3. Place the adhesive tape over the cap.
4. Put the cap with the tape in contact with the perianal area.
5. Return the adhesive tape to its initial position, preventing bubble or crease formation in this process.
6. Remove the cap from the glass and throw it away. Store the glass in its box.
