How long can a dog's stool sample be stored? - briefly
A dog's stool sample can typically be stored at room temperature for up to 48 hours. For longer storage, it is recommended to refrigerate the sample at 4°C (39°F) for up to one week.
How long can a dog's stool sample be stored? - in detail
The duration for which a dog's stool sample can be stored depends on several factors, including the intended use of the sample and the storage conditions.
For diagnostic purposes, such as detecting parasites or bacteria, freshness is crucial. In these cases, the sample should ideally be analyzed within 24 to 48 hours after collection. Prolonged storage can lead to degradation of the sample, making it less useful for accurate diagnosis. If immediate analysis is not possible, refrigeration at temperatures between 39°F and 46°F (4°C and 8°C) can extend the shelf life to up to one week.
For genetic testing or molecular diagnostics, such as detecting specific DNA sequences, the sample should be stored in a manner that preserves its integrity. Freezing at temperatures below -4°F (-20°C) is often recommended for long-term storage, which can extend the viability of the sample for several months to a year. However, it's important to note that repeated freeze-thaw cycles should be avoided as they can degrade the DNA and reduce the accuracy of the test results.
In summary, the duration for which a dog's stool sample can be stored varies greatly depending on the intended use and storage conditions. For diagnostic purposes requiring fresh samples, analysis within 48 hours is ideal. For long-term storage, particularly for genetic testing, freezing at low temperatures is recommended to maintain sample integrity.
