My Endo rang me & told me my Vit b12 was low and was asking my GP to prescribe me something and I picked up my prescription days later. I was left folic acid. Then a few days later I received blood test results through the post and it says

Serum vitamin B12 (GD)-folate low script done.

Shouldn’t I have been prescribed cynacobalimin rather than folic acid.

many thanks

Well, that says folate is low and folic acid prescribed. It doesn't say B12 is low. I expect folate was tested as part of the B12 test. What is the actual result for B12, it's not shown in your picture.

You've managed to chop your actual test results and reference ranges off in your photo, and just left the names of the tests.

Can you take another picture and replace the one you posted? You can edit your post (and replace the picture) by clicking on "More" directly under your post, click on Edit, make the changes you need to make and then click on Post.


For full Thyroid evaluation you need TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common when hypothyroid especially if you have Hashimoto's (high thyroid antibodies)

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or vitamins

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should ideally be done as early as possible in morning and fasting. When on Levothyroxine, take last dose 24 hours prior to test, and take next dose straight after test. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)

May not be able to see your folate and B12 results, but can see your results are high lighted that cholesterol is high. This linked to being hypothyroid
