I managed to find the following information about the LH, FSH and TPOab tests and reference ranges. Be aware that reference ranges can and do vary. Small variations occur due to the test technology and manufacturer, how the range was established, and due to the use of different units. (Seems to me that the UK is usually fairly consistent in units used.)
The site does have details of many, many tests and could be very useful.
Luteinising hormone (LH)
NB Not recommended for the routine diagnosis of the menopause
Thyroid peroxidase (TPO) antibody (TPO, anti TPO, anti thyroid peroxidase, anitthyroid antibodies)
Routine thyroid autoantibody test to help predict clinical hypothyroidism, usually in patients with increased TSH.
TPO antibodies at high titre are found in patients with Hashimoto's thyroiditis (95%), primary myxoedema (90%) and Graves disease (18%). Low titre TPO antibodies may occur in goitre, thyroid carcinoma and in other organ-specific autoimmune diseases e.g. PA. Antibodies may be predictive of future thyroid disease so clinical and biochemical follow up is advised.
For the antigastric parietal cell ab the site has this:
Gastric parietal cell (GPC) antibody
These are present in individuals with autoimmune gastritis and pernicious anaemia. However they are not specific for these conditions, as they may be also found in healthy individuals, particularly with increased age, and in those with other autoimmune conditions (thyroiditis, Addison’s Disease, IDDM). If Vitamin B12 levels are low then intrinsic factor (IF) antibody should be requested in addition to gastric parietal cell antibodies. These will be sent to an external laboratory. GPC antibody is more sensitive but less specific for pernicious anaemia than IFantibody.
