![]() Haseltine, Forbes, 27 June 2022 Passengers departing on Cathay Pacific flights to Hong Kong will be able to obtain polymerase chain reaction tests for the coronavirus at San Francisco International Airport’s onsite facility, the airport announced. 2022 Maternal SARS-CoV-2 infection was confirmed via polymerase chain reaction (PCR) test, the gold standard for diagnosis. 2023 But groups from Sweden and France, who used the highly sensitive polymerase chain reaction (PCR) assays to detect viral genetic sequences, showed that in those countries, spikes of rhinovirus infections in late summer delayed the peaks of influenza until late fall, the normal start of flu season. Emilie Le Beau Lucchesi, Discover Magazine, 22 Mar. We work to ensure that our wide and growing catalogue of tests is tailored to your needs, as we know that knowledge is the key to making our clients’ work easier.Recent Examples on the Web In this process, the DNA is chemically extracted from the sample, and a polymerase chain reaction is used to amplify the DNA segments. At Ambar Lab we offer more than 3,000 laboratory tests, support in business management and the development of new projects. In this way, infections can be prevented and treatment can be applied quickly.Ĭontact us if you have any questions and visit our blog to keep up to date with all the latest clinical news. In some diseases, such as tuberculosis, rapid diagnosis is key to limiting the spread of the disease and to promptly prescribe the appropriate treatment.Īnother advantage is that it can detect most of the currently known infectious agents in many different types of samples (blood, faeces, biological fluids, tissues, surfaces, etc.).Īt Ambar Lab, we have a wide PCR detection catalogue for the most common infectious pathogens and also for those less prevalent in our society.Īs we have seen throughout this blog post, the PCR technique is ideal for early detection of infectious diseases. Its specificity and high sensitivity are its greatest strengths, despite higher costs than other laboratory techniques. ![]() What are the advantages of these tests?Īs mentioned above, this type of testing has great advantages over other traditional methods. However, there is a rapid evolution from day to day: more and more results are obtained more quickly and easily, the complexity of the instruments is reduced and more qualified personnel are available. However, the performance of such tests is complex, requires specialised staff and is costly, especially for low-resource laboratories, as it involves not only high cost issues, but also specific facilities and automated equipment. Today, the incorporation of the PCR technique in laboratories has greatly improved the detection of infections and the number of companies developing these tests has greatly increased and continues to grow. In short, these tests detect them much earlier than other screening methods. By recognising and amplifying specific areas of the pathogens’ genetic materials through so-called nucleic acid amplification tests, early diagnosis of HIV, HBV, HCV, Covid infections is generated. Currently, dozens of countries apply such tests to detect human immunodeficiency virus (HIV) as well as hepatitis B virus (HBV) and hepatitis C virus (HCV) or the well-known SARs-Covid 2. PCR testing for infectious agents started in the early 2000s and is very accurate for microbial nucleic acids and can detect very low levels of infectious agents. This is not the case with antibody or antigen tests, as these appear in the blood after a period of time, and not immediately. These tests are primarily used for the early detection of a disease. Now, let’s look at what PCR tests are for and what their advantages are. RT-PCR and PCR are used to analyse microbial DNA/RNA levels in clinical samples. The nucleic acid sequence formed is the ideal molecular fingerprint that aids in the identification of many viral pathogens. ![]() Viruses or bacteria have an abnormal complement of DNA or RNA. In this blog post, we’ll give you the lowdown on everything you need to know about PCR testing. These differences make the PCR technique ideal for detecting infectious diseases, cancer and all kinds of genetic disorders. The genetic material of all living beings is composed of RNA or DNA, however, there are differences in the genome sequences of each one, which allows them to be detected in a specific and precise way. nucleic acids directly from the pathogens. These tests differ from those that detect antibodies or antigens, as the PCR technique involves the recognition of genetic material i.e. PCR testing for infectious agents is a molecular technique that seeks to detect viruses or bacteria directly. ![]()
