Best Time to Collect Saliva for DNA Test
By following the recommended best practices for saliva collection, you can increase the likelihood of obtaining high-quality DNA samples for accurate and reliable testing results.
The ideal time to collect saliva for DNA testing is typically when you have an empty stomach. It is recommended to wait at least one hour after eating a meal before collecting your saliva sample. This helps ensure that there are no food particles or other contaminants present in your saliva, which could interfere with the DNA extraction process.
Before collecting your saliva sample, it is advisable to rinse your mouth thoroughly with water to remove any lingering food particles or residue. Allow at least ten minutes to pass after rinsing before collecting your saliva. This waiting period ensures that your saliva is not diluted and contains an optimal concentration of DNA-containing cells.
There are two primary methods for collecting saliva samples for DNA testing:
Regardless of the method used, it is crucial to follow proper handling procedures to protect the integrity of the DNA sample. This may include using clean, disposable gloves and storing the collected sample on ice or freezing it immediately after collection.
To ensure an optimal DNA yield from your saliva sample, it is essential to follow any specific instructions provided by the testing laboratory or kit manufacturer. Some factors that can affect the quality and quantity of DNA extracted include:
