Specimen preservation
Some views on specimen preservation
One week can be stored at 2-8 degrees, and one month can be stored at -20 degrees. -80 degrees can be stored for more than 1 year. -196 degrees can be stored for more than 10 years
Q: If it is preserved according to this standard, will it have no effect on the result?
Answer: No, it definitely has an impact, but only within the range allowed by the error.
No matter how good you are, it will have an impact if you grow longer.
Samples that meet the above conditions will not have a substantial impact on the test results.
In other words, if the sample is maintained in this way, the result of the test during this time is meaningful. Of course, it is necessary to exclude the possibility that the sample had problems before it was saved.
Suggest:
1. There must be a complete plan before collecting specimens, and it must be clear whether the components to be tested are sufficiently stable.
2. It is recommended that fresh specimens be tested as soon as possible, and timely testing after collection. Samples tested in about 1-3 days can be stored at 4 ℃ for later use. If you need to collect specimens periodically for special reasons, please pack the specimens in a timely manner and store them at -20 ℃ or -70 ℃ to avoid repeated freezing and thawing.
