Why do I have to enter the lot number of my kit into the app and where is the lot number found?

In order to generate accurate data, the app requires that you enter the lot number because different lots of Lenti‑X GoStix Plus yield slightly different standard curves (similar to an ELISA). The lot number can be entered by scanning the QR code located on the GoStix cassette pouch, or it can be entered manually. Please do not use the QR code/lot number on the box.
