Question

Can two tests give different results?

Tested using first response, and Superdrug own brand test. Using the same urine sample. This is two weeks after period was due. Superdrug said yes pregnant. First response a very clear negative.

Very confused....

Hi, as far as I know false positives are almost impossible whereas false negatives do happen. Best of 3 with a clear blue digital (Amazon is cheapest)
Good luck!

The test could be designed to pick up different levels of hcg. One could detect as little as 20ml and the other as much as 50, which would take longer to come back positive. I think the more expensive ones detect the less amount, which is why you could use them sooner!
