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.
