Normal, but declining CBC & TSH

[scout]

I'm kind of a stats geek, so I've been logging my labs over the past 17 months, and noticed some trends. Everything is within normal range (though often on the low end), but many numbers are declining.

For example:
WBC                  9                      5.6                   6                  4.8               4.8
RBC                   4.09                 3.78                 3.82              3.84            3.8
Hemoglobin      12.9                   12                   11.9                  12               11.7
Hematocrit        38.8                 35.7                36.3                36.3            34.3    
Platelets            353                  398                 319                  277             276

TSH                    2.17                                         2.06                1.83

Other facts:
That last column is from August, when I had shingles
I've also lost 19 lbs (12.5% of total weigh) from January-October 2017, without trying. It seems to have tapered off now.
I'm 45, a healthy weight, exercise regularly, and my BP and HR are excellent, if not too low.

Since everything is still in range, I'm not too stressed about it. Just wondering if it's worth keeping an eye on, of if this is just what getting older looks like.

Hello~If keeping readings like this don't stress you out, then it is perfectly fine to continue to keep records. However, as my Naturopath told me, blood work especially thyroid panels, are just a "snap shot" of what is going on that second, so, I wouldn't stress out too much about those readings.

Just keep taking care of yourself, eat healthy take good vitamins and mineral, drink plenty of water and exercise, you should lead a nice, healthy, normal life.

Oops! Wrong info on WBC above.

WBC: Optimal Range: 4.0-5.5 Th/cu.mm

Adding this info from Dr Kaslow's article - Blood Cell Count. The article goes into what lowers or increases these labs.

WBC: Optimum values for an adult male is 14.0 to 15.0 g/dl and for an adult female is 13.5 to 14.5 g/dl.

RBC: Optimal values for an adult male are 4.70-5.25 million/mm3 and for an adult female are 4.00 to 4.50 million mm3."

Hemoglobin: Optimum values for an adult male is 14.0 to 15.0 g/dl and for an adult female is 13.5 to 14.5 g/dl.

Hemocrit: Optimum values in an adult male are 42.0 to 48.0% and in an adult female is 39.0 to 45.0%.

Platelets: Optimum values: 230,000 to 400,000 mm3.

You are being very proactive with you health which is great.


Excerpt from Life Extension -
Thyroid Regulation Testing Thyroid Function...

"Life Extension suggests an optimal level of TSH between 1.0 and 2.0 µIU/mL, as some studies have noted that a TSH above 2.0 may be associated with adverse cardiovascular risk factors.26 In addition, a TSH between 1.0 and 2.0 µIU/mL has been associated with the lowest subsequent incidence of abnormal thyroid function.66"
