Q & A

  • What are universal precautions that should be taken while collecting samples?

    -Universal precautions include using barrier protection, wearing gloves when handling body fluids, wearing a face mask or goggles, and being cautious when handling sharp objects like needles and syringes.

  • Why is it important to clean the work area and use disinfectants?

    -Cleaning the work area and using disinfectants is crucial to prevent cross-contamination and ensure the accuracy of the samples collected.

  • What should be included in proper sample labeling?

    -Proper sample labeling should include the patient's name, clinical specimen type, the site where the sample was taken, a unique ID number, specimen type, date, time, and place of collection, and the initials of the person collecting the sample.

  • Why is the requisition form important for sample processing?

    -The requisition form is important because it provides essential patient information and clinical history, which are necessary for accurate diagnosis and reporting.

  • What are the common types of body fluids that may require collection for microbiological analysis?

    -Common types of body fluids for collection include blood, urine, ascitic fluid, pleural fluid, and pericardial fluid.

  • How should blood samples be collected for culture?

    -Blood samples for culture should be collected using a sterile technique, with the appropriate volume depending on the patient's age and condition, and transported to the laboratory in specific culture bottles.

  • What are the different methods for urine sample collection and which is the most common?

    -The different methods for urine sample collection include clean-catch midstream, catheterization, and suprapubic aspiration. The most common method is clean-catch midstream urine.

  • Why is it important to avoid contamination when collecting stool samples?

    -Contamination of stool samples can lead to false-positive results, so it's important to collect the sample in a sterile container and avoid contact with disinfectants or the toilet environment.

  • What are the criteria for rejecting a sample in microbiology?

    -Samples may be rejected if there is a mismatch of information on the label and request form, improper transport temperature, delay in transportation, insufficient quantity, leakage, or if collected without a requisition form.

  • How should samples be transported to ensure their integrity?

    -Samples should be transported promptly to the laboratory using appropriate containers and transport media, and kept at the correct temperature as specified for the type of sample.
