Validation of urinary reproductive hormone measurements using a novel smartphone connected reader.

Home use tests to monitor hormone trends during the menstrual cycle have been available over-the-counter for a long time. However, these tests often depend upon manual readouts and hence may lead to false analysis. Furthermore, a lot of these tests are also not quantitative.

Predicting serum hormone concentration by estimation of urinary hormones through a home-use device.

Study Question: Can a home-use device be used to predict serum hormone levels?

Summary Answer: A home-use device can predict urinary hormone values which are well-correlated to serum concentrations of respective hormones and hence can be used as a proxy for serum measurements.

What Is Known Already: Home-use devices that predict ovulation are calibrated against the actual day of ovulation. However, the correlation of any quantitative system to serum hormone concentrations has not been established.
