At a glance
Hormone blood tests investigate specific questions about menstrual or reproductive health. The right tests and collection timing depend on your symptoms, cycle and medical history. A doctor should explain what a requested test can and cannot establish.[10]
Start with the reason for testing
Changes in periods have several possible explanations. RCPA’s amenorrhoea guidance describes different investigations according to the clinical situation. A doctor can decide whether hormone measurements, pregnancy testing or another investigation is useful. An online list of markers does not establish which tests you need.[10]
FSH and oestradiol
FSH helps regulate ovarian function. Oestradiol, also written estradiol, is an oestrogen. Results need their units and laboratory reference intervals. RCPA describes FSH intervals as method dependent and related to the menstrual cycle. Ask the requesting doctor which cycle information the laboratory needs.[3]
Collection timing is part of the referral
Tell your doctor the date of your last period and whether your cycle is regular. Mention hormonal contraception and other medicines. Follow the instructions attached to the particular request rather than choosing a collection day from a generic internet schedule. Ask the clinic if the timing is unclear.
Testing around menopause
At the expected menopause age, testing hormone levels is usually unnecessary for diagnosis. Jean Hailes says doctors assess changes in symptoms and periods, and may investigate other possible causes. Home blood or saliva tests marketed to predict menopause are not recommended.[2]
What the provider panel field means
The comparison records markers only when the provider publishes them. An empty marker list means the source did not establish the panel. It does not mean the laboratory cannot perform a test. Confirm the requested markers and any separate collection fee before paying.
Arrange a results discussion
Ask who will explain the report and how the result changes the next step. Check whether that discussion is included or needs a follow-up appointment. Keep a copy showing the collection date, units and laboratory ranges. You do not need to upload results to Hormone Test to use the comparison.
