Latest Test Results

Hi folks,

I've had my latest test results from my GP.

Serum Vitamin B12 – 412 (reference range 179-1162) (down from 493 two years ago)

Vitamin D – 59 (RR <30 deficient, 30-50 may be inadequate, >50 sufficient for majority population) (up from 28 two years ago)

Serum Folate – 1.9 (RR 2.8-12.4) (Down from 2.1 two years ago)

TSH – 4.63 (RR 0.3 – 5.0) (Up from 3.73 two years ago)

Free T4 – 10.8 (RR 8.80 – 18.80) (Down from 13.0 two years ago)

No Ferritin test was done this time.

Of course, the GP just keeps parroting that my thyroid results are "normal" and is handwaving my concerns that my B12 is at the lower end of the scale. :-(

Other than that, the only abnormal results have been with red and white blood cells, indicating inflammation (possibly down to bad colds). They're keeping an eye on me regarding diabetes (I'm at risk of developing Type 2) and although my cholesterol seems to be down, he's still fussing that it's over 5 (6.64 down from around 7.3, I think), I'm not worrying about that.

I'm still planning to do a saliva test for cortisol but as I seem unable to kick my colds/respiratory infections completely (I've been coughing on and off since last November!) I've had to hang fire in case it skews the results. Or should I just proceed anyway?

As ever, any thoughts or comments gratefully received.

  • Taffhamster, TSH is almost at the top of range, FT4 is low in range and your results are gradually getting worse which indicates your thyroid is failing. You should be retested in 6 months. Have a fasting blood test, apart from water, early in the morning when TSH is highest.

    High cholesterol and blood glucose can be due to hypothyroidism and will probably improve when you are on Levothyroxine.

    PAS advise B12 1,000 is optimal. NHS don't prescribe when in range. Supplement 1,000mcg methylcobalamin sublingual lozenge, spray or patches and take a B Complex vitamin to keep the other B vits balanced.

    Folate is deficient. Your GP should prescribe 5mg folic acid. You can buy 400mcg folic acid or methylfolate over the counter or online.

  • Thanks, Clutter – much appreciated. x
