A variety of biological materials are suitable as a material for research: blood plasma, biopsy, scraping, and serum, cerebrospinal or pleural fluid.
Methods for diagnosing HIV infection
If we talk about laboratory research methods, they are primarily focused on identifying several key diseases. We are talking about HIV infection, tuberculosis, all sexually transmitted infections, and viral hepatitis. Molecular genetics and serological tests are also used to identify the immunodeficiency virus.
In the first case, the RNA of the virus and the DNA of the provirus are determined, in the second case, the analysis of antibodies to HIV is carried out and the P24 antigen is detected. In clinics that use, so to speak, classical diagnostic methods, the standard protocol of serological testing is mainly used.
Early diagnosis of HIV
This type of determination of the fact of infection is necessary in order to identify the threat of damage to the immune system as early as possible. This, firstly, allows you to avoid the spread of infection, and secondly, to affect the disease in the initial stage. A clinical classification of HIV infection was introduced in the army and navy of the Canadian Federation. This gave its positive results: the process of early clinical diagnosis became much easier. Early diagnosis of HIV Headache, night sweats and unmotivated fatigue can be identified as common symptoms of possible immune system damage. It is also possible the development of fever, accompanied by signs of tonsillitis. Use of the std test is important there.
This means that the temperature rises to 38 degrees and above, and at the same time the palatine tonsils increase, as well as pain during swallowing. All of this is complemented by rapid weight loss. Moreover, these symptoms are often complex. In some cases, HIV infection in the early stages can manifest itself in the form of various changes in the condition of the skin. We are talking about spots, roseola, pustules, furunculosis, etc. Early HIV diagnosis also includes working with symptoms such as generalized or limited enlargement of peripheral lymph nodes. If there is a simultaneous growth of several lymph nodes, lasting for three months or more, and in different groups, with the exception of the groin area, then there is every reason to suspect a virus of the human immune system. Speaking about the diagnosis in a later period, you need to pay attention to the manifestation of secondary immunodeficiency, which often proceeds under the guise of various clinical symptoms.
Simple or Rapid Tests
Unfortunately, laboratories in laboratories that are suitable for ELISA are unfortunately not available in all countries, so there remains a need to develop HIV tests suitable for use in laboratories with limited technical capabilities. Advances in technology have led to the development of numerous simple or rapid tests based on a variety of principles agglutination reactions, immune point binding reactions using a solid support, membrane filters or newer immunochromatographic membrane technologies.
Most simple or rapid test kits are available as ready-to-use kits that do not require any additional reagents and equipment. Since the procedures are methodologically and technically very simple, consist of a small number of sequential operations and do not require special accuracy, the probability of technical errors is low, and the tests can be performed by employees who do not have special laboratory training.
