RAPID TESTS
Immunochromatography tests, or rapid tests, are a type of rapid diagnostic test based on the detection of the presence or absence of certain substances in a biological sample (blood, urine or saliva, among others). The process involves the capture of particles bound to specific antibodies or antigens that pass through a membrane, on which specific antibodies or antigens have also been immobilized, allowing the quick and easy detection of the presence or absence of the target substance in the sample.
These tests are ideal for application in clinics and other points of patient care because they allow results to be obtained quickly and reliably. In addition, their simplicity means that no equipment or specifically trained personnel are required, so that the patient is able to leave the clinic with an indicative diagnosis after the test.
For all these reasons, rapid tests are a great tool to determine whether more expensive and invasive subsequent tests are necessary, and they can be used as a guide to orientate the patient’s diagnosis and management. thus avoiding the prescription of drugs or invasive tests in situations where they are not necessary.
MOLECULAR DIAGNOSTICS
Molecular diagnostic tests are used to detect the presence of genetic material, such as DNA or RNA, in a biological sample susceptible to a disease-related gene or pathogen related to a disease.
These tests use molecular techniques that allow amplification of the genetic material present in the sample in order to identify what is to be detected by hybridization of the amplified fragments through specific probes.
There are different methods for hybridization, such as the reverse blot technique of Opegen products, which uses probes immobilized on a membrane to detect up to 24 different sequences in a single test.
In contrast, in the real-time PCR technique, hybridization occurs by the use of fluorophore-labeled probes during the PCR amplification process, allowing the detection of up to 4 different sequences in a single test. This technique is used for the PCR rt products and is quick and easy to perform.
