What Is Urinalysis Procedure?
The urinalysis test involves the collection of urine sample in a specimen cup. The proper collection of a sample is very important in order to avoid contamination of urine.
The collection technique is different for men and women. Alcohol wipes should be avoided as these may irritate the area.
This technique is called the mid-stream clean catch urine sample collection.
Other collection methods may be necessary depending on the specific situation. Frequently, hospitalized patients may have a urinary catheter (Foley catheter) placed in the bladder that directly drains urine from the bladder into a bag. The nursing staff simply collects the urine from the collection bag into the sterile cup. Samples can be collected from babies and toddlers who are not yet toilet trained by attaching a small collection bag with a bandage-type adhesive to the external genital region.
The collected urine sample should be analyzed soon (within 1-2 hours) after collection. If this is not possible, then the sample may be refrigerated.
