Urine collection for basic urine analysis and pregnancy test
  • First morning void urine
  • Before taking the sample, wash your hands with warm soapy water and thoroughly wash the urethral region with warm water and soap or an intimate hygiene wash. For women, hygiene in the area of the labia is particularly important, and the washing itself should be done from the front towards the anus, never in the opposite direction. Men are advised to thoroughly clean the penis.

  • Once you have started to urinate, collect a "mid-stream" urine sample, this means you do not collect the first or the last part of urine that comes out, you collect it in the middle of urination. The collected urine sample for the general examination should have for at least 15-20 milliliters.
  • Avoidance of urine examination during menstrual bleeding and 2 days before and 7 days after menstruation.
  • The container with the collected urine sample should be sealed and delivered to the collection point as soon as possible (not more than 2 hours). If the sample can not be delivered immediately after collection, place the container in the refrigerator (do not freeze it) and bring it to the test as soon as possible.

  • Urine collection for basic urine analysis and pregnancy test
  • Don't save the urine from your first time urinating. Flush this first specimen, but note the time. This is the start time of the 24-hour collection.
  • All urine, after the first flushed specimen, must be saved, stored, and kept cold. This means keeping it in a refrigerator (2-8 ºC) for the next 24 hours.
  • Try to urinate again at the same time, 24 hours after the start time, to finish the collection process. If you can’t urinate at this time, it is OK.
  • Once the urine collection has been completed, the urine containers need to be taken to the lab as soon as possible.
