Topic: Wondfo Tests LOT W00170116-3 Exp 1-10-2019
There has been a bad batch of Wondfo's discovered. LOT # W00170116-3 with Exp date 1-10-2019. Apparently these were sold from NUMEROUS online vendors and have been having issues with false positives, indents, and evaps. IF you are using tests from this batch, you should definitely confirm with a different brand of test before getting excited or stop using them all together.
I have not contacted Wondfo to confirm, but this has been posted on numerous forums and a fair about of lades have reported having false positives (doctor confirmed) with this batch.
