Diagnosis of infectious diseases

Diagnosis of infectious diseases
Infectious diseases - a large category of diseases, united by a common origin: they are caused by pathogens, ie viruses, bacteria or protozoa.Timely diagnosis of infectious diseases is needed to determine the most appropriate treatment.

all infectious diseases can be divided into groups according to the localization of the disease and the nature of the causative agent.

On localization of the disease infectious diseases is divided into disease integument, respiratory tract infections, intestinal infections, infectious diseases of the circulatory system, the transmission of infection with a variety of mechanisms (eg, enterovirus infection).

By the nature of infectious agents are divided into bacterial, viral, fungal, protozoal (caused by protozoa organisms), prion (called a special class of proteins - prions without nucleic acid and causing severe CNS pathology).

All infectious diseases vary in severity, but even an infectious disease with a relatively mild symptoms is dangerous for the body.

Diagnostics of infectious diseases

diagnosis of infectious diseases is carried out using the following methods.

  1. clinical method, or symptomatic diagnosis.The survey and examination of the patient can detect symptoms of the disease and to determine the range of possible infectious diseases.
  2. objective examination of the patient: the existence and nature of the rash, the condition of mucous membranes, tongue, lymph nodes.
  3. epidemiological methods (anamnestic).Gathering information about your stay in endemic foci, with infectious patients contact, ingestion of contaminated food of vaccinations, etc..
  4. Laboratory methods for the diagnosis of infectious diseases.

That laboratory diagnosis plays a critical role in the diagnosis of infectious diseases, so infections in laboratory diagnostic techniques is to dwell.

Laboratory diagnosis of infectious diseases

All methods of laboratory diagnosis of infectious diseases is divided into two groups - nonspecific and specific methods.

nonspecific methods of laboratory diagnosis of infectious diseases include:

  • hemogram (full blood count);
  • proteinogramma (analysis of protein fractions of blood);
  • liver function tests;
  • urinalysis;
  • coprogram (kala research);
  • ultrasound of various organs;
  • electrocardiogram and electroencephalogram;
  • instrumental methods of gastrointestinal research.

Specific laboratory diagnosis of infectious diseases includes virological and bacteriological methods of diagnostics to isolate the causative agent of an infectious disease, microscopic examination of abjection, rapid diagnostics for the detection of pathogen antigens, serological diagnostics for the detection of specific antibodies, allergic skin tests.

It should be emphasized that the diagnosis of infectious diseases should be to use several methods at the same time as the negative results of laboratory diagnosis can not completely exclude the diagnosis.
