Study Notes
Urine Analysis
- The recommended time of day to collect urine for routine urinalysis culture and sensitivity test is in the morning, as the first voided urine is more concentrated and more likely to contain bacteria if present.
Urine Collection
- A sterile container is provided to prevent contamination of the urine sample, ensuring accurate test results.
- Before collecting urine for routine urinalysis, it is recommended to perform hand hygiene and clean the genital area with soap and water to prevent bacterial contamination.
Urine Characteristics
- The normal color of urine is yellow or amber.
- The recommended pH range for urine is 4.5-8.0.
Urine Specimen Collection
- A minimum of 10-15 mL of urine is recommended for routine analysis.
- The first voided urine in a 24-hour urine specimen collection is discarded to eliminate bacterial contamination from the urethra.
- Adding preservative to the 24-hour urine specimen helps prevent bacterial growth.
- Clamping the catheter for 30 minutes to 1 hour before collecting a catheterized urine specimen allows the urine to flow freely and reduces bacterial contamination.
Catheterized Urine Specimen Collection
- Clamping the drainage tube and emptying the urine into a container after genitourinary surgery is contraindicated, as it may introduce bacteria into the urinary tract.
- Obtaining a sterile urine specimen from a closed drainage system helps prevent contamination.
Fecalysis
- A sterile specimen container is necessary for collecting stool samples to prevent contamination.
- Asking a patient to defecate into a clean, dry bedpan or portable commode helps prevent contamination and ensures a clean specimen.
Creatinine Clearance Test
- High protein food intake should be avoided before performing a creatinine clearance test, as it can affect test results.
Glucosuria
- Assessing for glucosuria in urine is significant, as it can indicate underlying medical conditions, such as diabetes.
- Urine preservation is important to prevent bacterial growth and maintain the integrity of the sample.
