What is nucleic acid detection, that is, after collecting human secretions, under laboratory conditions, by analyzing the RNA gene sequence of the virus, using PCR amplification method for detection, and diagnosis of clinical etiology. At present, nucleic acid testing is the most effective testing method for early determination of whether a patient is infected with the virus, early detection and early treatment.
Nucleic acid detection swabs are divided into two types: nasal swabs and throat swabs. During the sampling process, the doctor will use a swab like a cotton swab to wipe the pharynx and tonsils, or the secretions around the nasal cavity. One touch", quick and painless. Medical institutions will disinfect the inspection area, and medical staff will also disinfect their hands to avoid cross-infection. Generally speaking, the sampling process is safe and clean, without worrying about the risk of infection.
So which types of swab preservation solutions are divided into after sampling? There are two types of swab preservation solutions, inactivated and non-inactivated. At the beginning, almost all types of swab preservation solutions used in the market directly preserve live viruses. Inactivated swab preservation solution. This preservation method will cause the medical staff in sampling, transportation and testing to face a higher risk of infection. In response to this situation, the front line of anti-epidemics needs to store swabs that can directly inactivate the virus. However, it should be noted that while inactivating the virus, it should also be considered whether the preservation solution can stably preserve the integrity of the viral nucleic acid, so as to prevent the nucleic acid in the sample from degrading before the test, resulting in "false negative" nucleic acid testing. The production of the inactivated virus preservation solution developed to avoid this problem.
To put it simply, nucleic acid detection swab preservation solutions can be divided into two categories. The inactivated preservation solution developed by Desheng is a swab preservation solution with lysis function, which contains lysis salts for inactivating viruses and lysis proteins to protect nucleic acids. The virus preservation and lysis are completed in one step. The other is a non-inactivated type of preservation solution. Contrary to the inactivated type, it can protect the integrity of the virus protein and nucleic acid. In addition to nucleic acid detection, it can also be used for virus culture research. The operating environment requirements for this preservation solution are also different. The inactivated environment does not need to be so strict, while the non-inactivated type has higher operating environment requirements due to the risk of virus infection.
How to use swab virus preservation solution 1. Before sampling, mark relevant sample information on the label of sampling tube. 2. According to different sampling requirements, use sampling swab to sample in corresponding parts. The specific sampling methods are as follows: a) Nasal swab: gently insert the swab head into the nasopalatine part of the nasal meatus, stay for a while, and then slowly rotate to exit. The other swab swabs the other nostril, immerses the swab head in the sampling solution, and discards the tail. (suitable for sampling with this product) b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with swab. Similarly, immerse the swab head in the sampling solution and discard the tail. (suitable for sampling with this product) 3. Quickly put the swab into the sampling tube (including virus transport fluid). 4. Break the sampling swab at the broken place and tighten the tube cover. 5. Freshly collected clinical specimens should be transported to the laboratory within 96 hours at 4 - normal temperature, and those that cannot be transported to the laboratory within 96 hours should be stored at - 70 â?? or below. The samples should be extracted as soon as possible after being sent to the laboratory. The samples that can be extracted within 24 hours can be stored at 4. If not, they should be stored at - 70 or below

General information One-step influenza a/b test is detection influenza type a and type b nucleoprotein antigen extracted from the nasal swab specimen. Sensitivity : 91.3% , specificity : 95.7% Detection limit:5.1x105tcid50/ml Specimen: nasal swab Reading time : 15-20min
Intended Use The Influenza A +B Test is a rapid chromatographic immunoassay for the qualitative detection of influenza type A and B nucleoprotein antigens in nasopharyngeal swab and nasal aspirate specimens. This kit is intended to be used as an aid in the diagnosis of influenza A and influenza B virus in nasal swab specimens. Principle The Influenza A +B Test is a qualitative membrane strip based immunoassay for the detection of influenza type A and B nucleoprotein antigens in nasopharyngeal swab and nasal aspirate specimens. In this test procedure, influenza type A antibody is immobilized in the A line, influenza type B antibody is immobilized in the B line. After a specimen is placed in the specimen well, it reacts with influenza type A antibody and/or B antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized antibody. If the specimen contains influenza type A, a colored line will appear in the A line region indicating a influenza type A positive result. If the specimen contains influenza type B, a colored line will appear in the B line region indicating a influenza type B positive result. Absence of any T lines (A and B) suggests a negative result. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred. Storage and Stability 1.Store as packaged in the sealed pouch at room temperature or refrigerated (4-30â?? or 40-86â??). The test device is stable through the expiration date printed on the sealed pouch. 2.The test must remain in the sealed pouch until use.
One Step Influenza A Test is a rapid qualitative assay that detects influenza type A (including the subtype H1N1) nucleoprotein antigen extracted from the nasal swab specimen. The device is used to aid in the diagnosis of influenza type A infection. For in vitro diagnostic use only. For professional use only. Influenza A SUMMARY Influenza (commonly known as flu) is a highly contagious, acute viral infection of the respiratory tract. It is a communicable disease that is easily transmitted through the coughing and sneezing of aerosolized droplets containing live virus. Influenza outbreaks occur each year during the autumn and winter months. There are three types of influenza viruses: A, B, and C. Only influenza A viruses are further classified by subtype on the basis of the two main surface glycoproteins hemagglutinin (HA) and neuraminidase (NA). Influenza A subtypes and B viruses are further classified by strains. Humans can be infected with influenza types A, B, and C viruses. Subtypes of influenza A that are currently circulating among people worldwide include H1N1, H1N2, and H3N2 viruses. Influenza B viruses can cause morbidity and mortality among humans, but in general are associated with less severe epidemics than influenza A viruses. Although influenza type B viruses can cause human epidemics, they have not caused pandemics. Influenza type C viruses cause mild illness in humans and do not cause epidemics or pandemics. Influenza A PRINCIPLE One Step Influenza A Test is a rapid immunochromatographic test for the visual detection of influenza type A antigen (nucleoprotein) extracted from the nasal swab specimen. The test adopts double antibody sandwich method. When the extracted specimen is added into the test device, the specimen is absorbed into the device by capillary action, mixes with antibody-dye conjugate, and flows across the membrane pre-coated with influenza type A monoclonal antibody. When the influenza type A antigen levels are at or above the target cutoff (the detection limit of the test), type A antigen in the specimen binds to the specific antibody-dye conjugate and are captured by influenza type A monoclonal antibody immobilized in the relative site of test region T of the device. This produces a colored test band in the test region. When the influenza type A antigen levels are zero or below the target cut off, there is not a visible colored band in the test region of the device. This indicates a negative result for influenza type A.
