freeze urine while he is clean. store in very good freezer.
Q- How long do your clean urine samples last and how should they be stored?
A- Samples should be stored in a refrigerator. If stored for extended periods of time then they should be frozen. The integrity of our samples is ensured by our proprietary vacuum seal. As long as the sample remains in its vacuum seal it may be kept at room temperature away from direct sunlight for days at a time. It will be good for up to six months, in the vacuum seal, if stored in the refrigerator. If frozen in the vacuum seal, it can last for about 1 year. Once the sample is removed from the vacuum seal, it should not remain at room temperature for more than 18 hours. It will keep in the refrigerator, unsealed, for 30 days. In the freezer, an unsealed bag can last up to 6 months.
Q- How should I thaw my frozen urine sample?
A- When ready for use drug free urine samples may brought up to acceptance temperature simply by running under hot water until the temperature strip displays between 90-99 degrees Fahrenheit. After thawing and achieving proper temperature make sure to shake the sample well so that any present particles dissolve completely. The samples should be thawed at a slow and constant rate so as to hinder crystals from precipitating. If crystals do form then the sample may be filtered through a clean white coffee maker filter.
Q- Does transportation affect urine and bacterial viability?
A- Customers often ask about the preferred method of transporting urine samples to the laboratory for culture, and the effect of transport time and storage temperature on the viability of organisms.
To address these questions, the following study was performed: Urine samples with pyuria (n=18) submitted to Antech's Houston laboratory were divided into several aliquots. One aliquot was inoculated immediately onto blood/MacConkey agar and cultured aerobically for 72 hours in the Houston laboratory. The urine aliquots were also placed into 3 tubes: RTT, grey top urine culture tube (Transport Kit), and Copan Swab for transport to Antech's Irvine laboratory, where they were stored at 4-8°C and at room temperature. They were next inoculated onto blood/MacConkey agar for aerobic culture and examined after 24, 48 and 72 hours.
Fourteen urine samples cultured positive for bacteria and 4 were negative. There was no observed effect of storage time, storage temperature, or type of storage tube on these culture results, or on the amount of bacterial growth (light, moderate or heavy).
Conclusion: Based on these findings, we consider that routine transport time does not influence urine culture results.
