Collecting your sample

How do I collect my sample?

Bristle profiles your oral microbiome by using a sample of your saliva. To provide your sample, you spit into a small tube containing a clear liquid solution that functions to stabilize your saliva. You mail back the tube to Bristle's laboratory using the prepaid envelope provided and results are returned online. Detailed step-by-step instructions of the sample collection process are included in each test kit and also available through your account dashboard after registering your kit.

When is the best time to collect my sample?

In general, wait at least 30 minutes after eating, drinking, or smoking before providing your saliva sample. The best time to collect your sample is first thing in the morning, before you've done anything else.

Does the kit expire?

Your Oral Health Test kit can be used up to 6 months after it is delivered. Our sample collection kit stabilizes your saliva sample so that it can be properly tested after a period of time. We recommend shipping your saliva sample back to our lab within two weeks of collection to ensure the quality of your sample and accuracy of your results.

What is the clear liquid in the collection kit?

This is called a "buffer" solution and helps preserve your sample after you send it back to us for analysis. We provide you with two collection tubes in each kit in case you spill the first one. Our buffer is non-toxic but we do not recommend consuming it.
