Just to add im on 75 mg levothyroxine .



Can you supply ranges for members to give a more comprehensive comment ?


While your b12 looks low I cannot tell as you haven't published the ranges.

Also try and list your results as it makes it easier read.

If you know where your blood tests are carried out i.e. which lab, then you can check the lab website. They may have posted the reference ranges they use. You can ask your surgery where they send blood for testing.

Alternatively, if the ref ranges aren't posted on the web you could email or phone the lab and ask if they could send you a copy of their reference ranges.

Thank you il have a look and update x


Results have meaning only when normal values are reported with the results. Normal values vary according to the methodology of the testing in the lab where the tests were run. Results should appear like so:

Ca: 8.6 mg/dl L (8.8-10.4) mg/dl

A flag of "L" or "H" may appear to indicate the result is abnormally low or high. Results only slightly low or high aren't necessarily significant but listen to what your Dr. has to say about them.

AP, please give us the normal values for your tests.


I am writing this as a trained, graduate and experienced laboratory professional and I am not guessing at any of this.

My dear suesz it has taken me this long to get my blood results printed . Iv had great difficulty with this surgery . And they made it very difficult to get blood results back as did doctor . I wil fill u in on this . The only levels they show on the test result page is for the ferritin . I feel very defeated now x


Awww, perk up, Andypandy. We'll get you fixed up. You can take these results to the next Dr. you get to replace this current one and let that Dr. explain it to you. It's hard to wait but at least you'll finally have someone you can believe in.

Thank you surez yes hoping for the best one to help me . Xxx



You know you are hypothyroid, so I'll list normal values for the other tests:

Inorganic phosphate: 0.68 NORMAL 0.97-1.45 mmol/L

Alkaline phosphatase: 87 NORMAL 37-98 U/L

Vit B12:307 NORMAL normal range: <200 pg/ml

Albumin: 47 INVALID RESULT normal range: 3.5-5.5 g/dl Could this result actually be 4.7?

Folate (folic acid/vit. B9): 11.6 NORMAL normal range: 2-20 ng/ml or 4.5-45.3 nmol/L depending on which method was used to measure it.

Calcium: 2.31 INVALID RESULT normal range: 8.5-10.2mg/dl

Ferritin: 158 NORMAL normal range: 11-307 ng/ml or mcg/L

Iron: 40 LOW normal range: 60-170 mcg/dl

Transferrin saturation: 78% HIGH normal range: 20-50% Levels greater than 50% suggest iron overload.

Transferrin: 2.06 LOW normal ranges: 170-370 mg/dl

Cortisol high normal.

Having the printed lab results in your hands would solve some of the mysteries of these invalid results and why your iron is so low while your transferrin saturation is so high.
