On the subject in the title: Reading a home test result without over-claiming — what changed since Working notes rather than a conclusion.

What changes if the standard account of Reading a home test result is wrong? I ask because I have been treating it as settled and I noticed this week that I could not say why.

Working through the consequences rather than the evidence, since others here are better placed on the evidence.

False positives and false negatives: no test has 100% sensitivity and 100% specificity. A negative result does not guarantee absence; a positive result does not guarantee presence. The predictive value depends on prevalence.

The answer changed when I changed how I was measuring, which was informative.

The most useful home practice is not a test at all: photograph the vial, the cake, the label and the document on arrival. It costs nothing and it is the evidence you will wish you had.

That is one dataset and I would not build a rule on it.
