Blood results and further test

[Quest10]

I have been experiencing some tingling (very mild) in the tips of some of my fingers (mainly left hand and most often in my thumb) for almost two months, on and off. I've also woken some nights with pins and needles but my doctor thinks it's unlikely to be carpal tunnel syndrome. It's more annoying than anything else. A doctor friend ran a series of bloods which came back fine except for a few which he said were relatively low but wasn't overly concerned. These were:
Adjusted calcium 2.03 (range 2.10-2.60)
Lymphocytes 1.31 (range 1.5-3.5)
Ferritin 19 (he said this wasn't very low but slightly).
All the others were in the normal range(Vitamin B12 was 231).
He has written to my own doctor to request repeating the bloods in about six weeks and also mentioned that I should have the parathormone level checked. However, overall he thinks it may be stress-related and that I may be subconsiously hyperventilating and thereby altering the blood calcium levels.
I'm wondering if any of these lower levels are linked with thyroid problems and also whether blood results in the lower range but not below the cut-off should also be of concern (e.g Vitamin B12 of 231). I wonder should I take a vitamin supplement in the meantime to see if it helps?  I am 32 years old and female. Many thanks for your time.

A multivitamin is reasonable and I agree with repeating labs including thyroid labs in 4-6 weeks.  The low ferritin is not unusual in menstruating women.  The B12 seems a little low -- I think most ranges are >400 so 231 is low.  Low B12 can cause some peripheral neuropathy which may be what you are describing.

I'm not familiar with TSH ranges.  My labs ranges are:
0.35 - 5.50 Euthyroid
0.00-0.11 Hyperthyroid
>5.5 Hypothyroid

My TSH came back at 0.73.  

Is this normal?

Thanks

Your TSH level is normal.
