Make It Secure and Trackable!

When the lab receives your sealed sample, it can verify that is hasn't been tampered with, maintaining a tight chain of custody. These checks keep you compliant and helps to verify the integrity of your product.
And last, but not least, Labeling. Clearly labeling your sample with the correct tracking information prevents confusion and ultimately with get your test results back to you sooner and more accurately. (We'll updating this section in the future with more specific labeling recommendations.)
