Hi becca
Please can you post your actual results. On its own SHBG will not tell you how much free testosterone is available although the normal range I gather is 18-144 nmol/l (not sure whether this is male or female as the sheet doesn't say). I presume Total T has also been measured? The range for women is 0.5 - 3 nmol/l. Some HRT increases SHBG (oral forms).
You need to calculate the Free Androgen index (maybe this has been done for you?) which is Total Testosterone divided by SHBG express as a percentage =- as long as they are measured in the same units.
Range for FAI is 0.5 - 6.5 %. (Chelsea and Westminster clinic give the range as 1-6). I got this info from the RCOG website here:
https://www.rcog.org.uk/globalassets/documents/careers-and-training/mrcog-exam/mrcog-normal-ranges.pdfAs for other tests - unless you need to know if you are still ovulating, and sepcifically for those who have fertility problems and are worrying about having sufficient progesterone - you do not need to have progesterome measured. If you are post-menopausal it will be low, as also in the first phase (follicular phase) of the normal menstrual cycle. After ovulation it rises.
Are you taking testosterone or other forms of HRT?
Thyroid is important but unless you present with specific (or some non-specific symptoms) this won't be requested. Usually only TSH is measured which is not conclusive as T4 needs to be measured and for those with conversion problem to T3 this too - although rarely done on NHS. Thyroid function is one of the most badly diagnosed/treated conditions on NHS. If underactive thyroid function is a problem you would be having fatigue, weight gain and feeling cold amongst the primary symptoms, with hair loss, constipation and dry skin also featuring! These symptoms also have other causes.
Hope this helps and good luck with your appointment.
