Help to understand blood results

[TasFish]

Hi there,

Help needed!

What does <9 IU/mL mean please.

The reference range for the results in question are 0.00-34.00IU/mL

Thanks 😊

Can you print all your blood results and ranges because that will give members a better idea of your over all health. TSH, T4 and T3 and antibodies. All your vitamin levels and ranges as well and a little history about your condition.

International units per millilitre. Whatever it is I would say your result was less than 9 and the reference (acceptable or normal) range 0 to 34 so you are within that range.

Less than 9 might be meaningful to doctors - lower third of range.

This is presumably TPO antibodies result. It says your antibodies were less than 9. A result over 34 would be positive for autoimmune thyroid disease

There are two different thyroid antibodies. TPO and TG antibodies.

Both need testing.

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

NHS refuses to test TG antibodies if TPO are negative

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or all 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 special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random
