What Tests Are Needed For Malnutrition + Malabsorption?

[integral]

I would like to test everything but don't know the correct names for each test or I am aware some tests are deceptive and don't really reveal the issue so id like to avoid the ones that aren't accurate.

What tests do you recommend? I feel like this is generally useful information for everyone on the forum.

Do you experience any symptoms related to a malnutrition/malabsorption-issue? 
Any GI stuff at all? 
Or is there a abnormal lab test showing defficiencies?

The thing is, once you just start randomly testing for potential functional inconsistencies, you can get lost very fast.
I am all for going beyond the ordinary in medicine, but there needs to be a clinical basis for that to be reasonable.

@undeather @Michael569 Its for me and my gf.

She has issues with losing hair, acid reflux and chronic low energy.

I have POIS, that takes about 4 days of recovery to go back to normal after ejaculation. Symptoms are sluggishness, poor digestion, lactic acid build up from exercise stops or disappears, brain fog.
