How to arrange hormone blood tests, including uncommon tests, in London

Читать на русскомHormone testing should answer a particular question about cycles, fertility, thyroid disease or treatment monitoring. An “all hormones” panel without a clinical question can add cost and ambiguous findings. Obtain a plan from your GP or relevant specialist first.
Establish the exact test and purpose
Request each analyte's name, timing and how the result could change care. Keep original overseas requests and your medication list. Similar names are not necessarily interchangeable.
For an uncommon test, ask the laboratory to confirm its code, sample type, referral requirements and collection availability at your chosen site. Establish whether testing is local or sent to a reference laboratory.
Agree timing before purchasing
Cycle day, time of day, medicines and preparation requirements vary. For example, progesterone used to assess ovulation is commonly timed about seven days before the expected period; “day 21” assumes a particular cycle length. UHNM laboratory: progesterone ↗.
Request individual instructions for irregular cycles. Disclose hormonal contraception, HRT, fertility medicines and supplements. Do not stop them yourself to obtain supposedly clean results.
Check costs and quality
Separate consultation, collection, individual tests and medical-review fees. Direct self-pay booking may apply only to the provider's listed tests. Nuffield Health: blood-test routes ↗.
Check laboratory accreditation and relevant scope through UKAS ↗. For specialised assays, establish turnaround, sample stability and collection timing; home finger-prick sampling is not suitable for every purpose.
Interpret results with the history
Obtain units, reference ranges, collection time and cycle phase where relevant. A single hormone measurement should not independently determine diagnosis or treatment.
Return to the requesting clinician to discuss repeat testing, another method or referral. Consider methods and units when comparing overseas and UK results. Persistent symptoms require follow-up even if a commercial report marks everything green.
