Study Notes

Specimen Collection

Wash hands before and after specimen collection to minimize contamination.
Collect specimens at the appropriate stage of the disease for accurate diagnosis.
Ensure the specimen represents the infection; for example, sputum for pneumonia, not saliva.
Securely close the container to prevent leaks during transportation.
Label and date the container clearly, and complete the requisition form for proper identification.

Urine Specimen Collection

The first morning urine sample is preferred because it has a consistent volume, concentration, and lower pH, ideal for preserving elements.
If a first morning sample isn't possible, note the time of collection on the test requisition.
Utilize break-resistant plastic containers instead of glass for urine specimens.

Sputum Specimen Collection

Analyze urine samples within 2 hours of collection for optimal results.
