B) The urine collection container handed over to the patient shall be labeled and the name shall be checked.
C) Inform the patient of the minimum sample size required for the experiment.
D) Instruct patients to avoid pollution during sampling.
E) After instructing patients to take samples, cover the container to prevent urine from overflowing, and record the sampling time.
Urine samples collected in a specific period of time (such as urine 2 hours after meals, urine collected immediately after prostate massage, urine 24 hours, etc.). ).
Pay attention to specimen collection
These matters are as follows:
A) When collecting regular urine samples, the patient should be informed of the start and end time of the time period; Urine should be emptied before retention.
After that, collect all urine discharged during this period (including the deadline);
B) If preservatives are bio-hazardous, patients should be advised to collect urine in a clean container without preservatives first, and then carefully pour urine into a collection container containing preservatives provided by the laboratory;
C) Adding different kinds of preservatives may interfere with the repeated detection of urine samples. When a variety of preservatives interfere with urine test results, urine samples should be collected separately for different test items (which can be collected in batches or at the same time
Can be retained at one time and packed in different containers);
D) Urine collected in a specific time should be kept at 2℃ ~8℃. For patients with bed catheterization, put the urine bag on the ice bag; If the patient can walk, the urine bag should be emptied regularly and the urine should be kept at 2℃ ~8℃.
E) When collecting urine for a period of time, if the collected urine exceeds the capacity of a single container, two containers must be used, and the urine in the two containers must be fully mixed before detection. The most common practice is to dump urine samples back and forth between two urine containers. The amount of urine collected in the second container is usually small, so the amount of preservative added is correspondingly reduced.
