Tracking nutrient levels and other substances in blood

If you could track any substance in the blood over time, as easily as you track your workouts, what would you want? Could be levels of specific vitamins, amino acids, supplements, hormones etc.

The reason I ask is because I'm developing a product that could easily measure substances from a drop of blood, and provide the information in a smart phone app, or something similar, so would like to know what people would like to know about.

Could be for lifting reasons or for general health reasons or anything else. If this is a topic that interests you please share!

Thanks

Insulina.

All vits and minerals see what I'm lacking

Electrolytes

Hormones

Blood sugar

Any way of telling if my RBCs are clumping together or if my RBC count is way too high?

If you get this up and running I would like to be a case study for you mate - someone 150kg and openly using gear would be a good candidate surely?

Blood sugar.

The market would be massive!

Test
Proteins if thats possible?
and basically what sam said and id also happily be a guniea pig.

Very surprised there isn't more interest in this

I spent some time putting some thought into this sort of thing a while back - there's quite a lot of problems to overcome in terms of making this sort of thing actually feasible (as I'm sure you are aware)...but if it could be done (and I think it can) then it would potentially absolutely revolutionise the way just about every physical activity is conducted, I really can't overstate the potential it has.

few iOS apps that do that you just need a few microlitres of blood a digital glucose reader and a means of getting that data into HealthKit

Me too bro, I know theres blood tests available with anaylsis that lets the athlete know what diet and suppliments thier body actually needs for optimum performance... But thats always been the reserve of national and international champions.

To have that tool on our arsenal at a grassroots level of lifting could,if properly used be a complete and utter game changer!

Pete Tregloan is a fantastic specimin of proof of this sort of testing.

Eddie hall said getting blood profile done and tweaking accordingly was the game changer for him..

I want the same as I am convinced it could put the 10% i need on my total for 1000.

I would definitely be interested in something like this!

Would be interested in taking this abroad. Lots of sick, old people who could do with a test like this.

I'd say blood lipids would be a good thing that would appeal to the general public.

Would obviously need to know what the results mean too. Or some idea of what levels of 'whatever' is being measured is normal.
Wouldn't this be expensive for individuals?

I can honestly say that, despite coming from a sports science background, I have no idea what I would like/want to track.

I think for this to be of interest to most people we would need to be told what we needed to monitor, what the optimum figures are and what to do about it if your results are less than ideal (together with the science to back it up).

I had an idea years ago about a device, perhaps like a modern day smart watch that was somehow connected to ones blood supply and able to measure blood levels in real time. It would then top up anything you were deficient in from a replaceable cartridge.

I suspect this is completely impossible.
