Types of Urine Samples
RANDOM URINE SPECIMEN
Most commonly received sample because of ease of collection and convenience for the patient. Specimen collected anytime of the day without prior preparation. Also known as Single Voided Urine/Occasional Urine.

Appropriate for routine urinalysis.
First Morning Urine Sample
-Urine collected upon rising from sleep
IDEAL urine sample for URINALYSIS
-Most acidic and most concentrated (retained in the bladder for 8-hours) -Optimal specimen for the preservation of cells and casts
-Also essential for confirming a doubtful pregnancy test and for evaluating orthostatic proteinuria. Second Morning Urine Sample
-Also known as Fasting Urine Sample
-This is the second voided urine after a period of fasting for glucose monitoring (diabetic patients). TIMED Urine Samples
-Used for the quantitative measurement of urine analytes (Sx of choice for crea clearance) -Since concentration of substances to be measured varies with daily activities, a 24-hour urine sample is required. Methods of Urine Collection

-Urine specimen obtained after a thorough cleansing of the glans penis (males) and the labia and urethral meatus (females). -Following the cleansing procedure, the patient passes the first portion of urine into the toilet, stops and collects the mid-portion in the specimen container. -This provides a sample that is less contaminated by epithelial cells and bacteria (normal flora). Methods of Urine Collection

CATHETERIZED SPECIMEN
-Specimen of choice for patient suffering from urinary retention. (Patient cannot void voluntarily) -The specimen is collected under sterile conditions by passing the catheter through the urethra into the bladder. -The specimen is used for BACTERIAL CULTURE.

-If routine urinalysis is requested, culture should be performed first to prevent contamination.

SUPRAPUBIC ASPIRATION
-Involves urine collection directly from the bladder by puncturing the abdominal wall and the bladder using a needle syringe. -Since the bladder is normally sterile, it is primarily used for bacterial cultures and for infants to whom contamination is unavoidable. -The only specimen acceptable for both aerobic and anaerobic urine culture. -Can be used for cytological analysis of urine

Urine Culture
