So no false positives? That’s probably why they kept on using it - if it grows, you can be sure that you’re pregnant.

- londons_explore 7y agoI can imagine it might be easy to optimize this test a bit... By repeating the test every few days, and looking at the patterns of grow/no-grow you would probably get a much better result.
- gus_massa 7y agoWith only 6 (8?) cases, the naive bound of the false positives is ~15% and if there is some statistician nearby the bound will be much higher. (I guess close to ~25%, but I'm too lazy to look up the correct calculation.)
- mamon 7y agoAnd if it doesn’t grow you can repeat the test in a week or two - even modern tests have this issue since early in the pregnancy hormone levels might not be high enough yet. Regarding false positives - since you’re detecting hormones that are not produced outside of pregnancy time, then the only possible reason for false positive could be some genetic condition, or maybe some serious endocrinologic disease, maybe ovarian cancer.
