Study Notes
Urine Collection for Tests
- Optimal urine collection time for routine urinalysis is the first morning specimen when the bladder is most concentrated.
- If a sterile container is unavailable, a clean, dry, and tightly sealed plastic bottle is recommended for immediate urine analysis.
Pre-Collection and Documentation
- Prior to urine collection, patients should be instructed to clean the genital area to minimize contamination.
- Documentation should include the date, time of collection, patient identification, and method of collection.
Urine Volume and Timing for Tests
- A minimum of 10-15 mL of urine is typically required for routine urinalysis.
- Urine specimens for culture and sensitivity tests should be sent to the laboratory as soon as possible, ideally within one hour of collection.
24-Hour Urine Specimen Collection
- To collect a 24-hour urine specimen, start with an empty bladder, then collect all urine for the next 24 hours in a designated container.
- The principle involves capturing all urine produced for 24 hours to accurately assess kidney function and substance levels.
Handling Missed Collections
- If a urine collection is missed during the 24-hour period, it should be documented, and the collection restarted from that point to ensure accurate results.
Catheterized Urine Specimens
- The purpose of collecting a catheterized urine specimen is to obtain a sterile sample, especially in patients unable to provide a clean catch sample, ensuring reduced contamination risk.
Creatinine Clearance Test Precautions
- Patients should avoid high-protein diets, excessive exercise, and dehydration prior to a creatinine clearance test to ensure accurate results.
Anemia Testing
- The Schilling test is used to confirm pernicious anemia, vitamin B12 deficiency, and intrinsic factor deficiency anemia.
Glucosuria Implications
- Presence of glucosuria in urine may indicate diabetes mellitus or other glucose metabolism disorders.
Stool Specimen Collection Purpose
- Collecting a stool specimen for fecalysis aims to diagnose gastrointestinal conditions, including infections and malabsorption.
Interpretation of Melena
- Melena indicates upper gastrointestinal bleeding, characterized by black, tarry stools.
Sterile Urine Specimen Collection Precautions
- Avoid touching the drainage system or using unsterilized containers when collecting a sterile urine specimen from a closed drainage system to prevent contamination.
