Haha yeah, I'm a physician and I can tell you there're few things worse then when a patient get all worked up about some number that is "0.1" too high/too low. It's usually totally meaningless, gives groundless anxiety and waste everyones time.
It's not easy to interpret these numbers and you have to have quite a deep understanding of statistics, i.e you can be in the normal range and be sick, and you can be outside and be healthy. Type i/ii errors, precision, accuracy, calibration etc etc. I'm sure hackernews knows what's up I'm sure.
It's said about 90% of all diagnosis can be made only on taking the history. Tests are normally only done to assure, quantify, guide treatment etc.
* Testosterone: I have no idea why you would be interested in measuring this at home and I strongly suspect this could lead to misguided treatment with severe side effects.
* Inflamation: Probably a C-reactive protein. Pretty much useless on it's own.
* Fertility: Not sure exactly what they measure but I guess LSH/FSH. This job can be more easily done with a thermometer.
* Vitamin D: If you are worried, get it checked ONCE. No need to check day to day. If you take a supplement, your body will regulate the rest.
* Influenza: Again, not sure what they are testing and why you would want to do this as there's no specific treatment. When you do a test, always reflect what you will use the result for.
IMHO this device lacks the "test" that actually would be useful, like
* glucose
* maybe TSH
* your weight
* your activity level
* your caloric intake
* your sleep
Because these are things that actually mean a lot to your general wellbeing.
