Taking or obtaining samples is the procedure that consists of collecting a biological sample of your body. This hardly presents risks. To guarantee the safety of the patient, it will be carried out by trained health personnel and under conditions of safety and rigorous asepsis. The handling of the sample is as important as obtaining it, so there are strict rules for the correct procedure, handling, transportation and conservation of the sample, as well as for its proper processing in the laboratory. The study (biochemical, cytological, microbiological, etc.) of biological samples can provide very useful information about the diagnosis or evolution of your disease, which will allow for more appropriate treatment.
