Hormonal Blood Test in Johor Bahru

There is no single "hormone test". Hormone levels are chosen to answer a specific question, and many hormones only make sense when they are taken at the right time and read alongside your symptoms. Common reasons and the tests usually considered: • Tiredness, weight change, feeling cold or hot, palpitations, hair loss: thyroid function — TSH, often with free T4 (and sometimes free T3). See thyroid test and thyroid disorders. • Irregular or absent periods, acne, excess hair growth, possible PCOS: LH, FSH, testosterone, prolactin and sometimes SHBG, plus glucose or HbA1c and a lipid profile because PCOS affects metabolic health. See PCOS. • Difficulty conceiving: FSH, LH and estradiol early in the cycle, progesterone in the second half of the cycle to check ovulation, prolactin and thyroid function. Ask whether AMH is available if your doctor or fertility clinic has requested it. • Menopause symptoms: in women over 45 with typical symptoms, menopause is usually diagnosed from symptoms and period pattern rather than blood tests; FSH can help in younger women or when the picture is unclear. See menopause symptoms. • Low energy, low libido or erectile problems in men: morning testosterone, often with SHBG, LH/FSH and prolactin if the level is low. See testosterone test. • Milky nipple discharge, headaches with period changes: prolactin. Starting with a short consultation means the doctor can pick the tests that answer your question, rather than a large panel that is hard to interpret.

Many hormone results are only meaningful if the sample is taken at the right time: • FSH, LH and estradiol: usually on day 2–5 of the menstrual cycle (day 1 is the first day of full bleeding). • Progesterone (to confirm ovulation): about 7 days before the next expected period — around day 21 in a 28-day cycle, later if your cycles are longer. • Testosterone: in the morning, ideally before about 10–11am, because levels are higher early in the day. A low result is usually repeated on a second morning before any conclusion is drawn. • Prolactin: stress, recent exercise, breast stimulation and some medicines can raise it, so a mildly high result is often repeated. • Thyroid tests: can be done at any time of day; if you take levothyroxine, ask whether to take your dose before or after the test. Fasting is not needed for most hormone tests. It is needed if glucose or insulin are being measured at the same time — in that case, fast 8–12 hours with water only. If you take the contraceptive pill or other hormonal treatment, tell the doctor: these change several results, and the timing advice above may not apply. Biotin (vitamin B7) in hair, skin and nail supplements can interfere with some hormone assays, including thyroid tests; you may be asked to stop it for a few days before testing.

At Klinik Muhibbah, the doctor first asks about your symptoms, cycle, medicines and any previous results, and examines you if needed (for example blood pressure, weight, thyroid or signs of excess androgen). The doctor then explains which tests are being ordered and when the blood should be taken — sometimes that means booking the draw for a particular day of your cycle. The blood draw takes a few minutes. Hormone tests are specialised tests, and how long results take depends on the test and the laboratory processing it; the desk will tell you when to expect your report. When results are ready, the doctor reviews them with you — in person, or by teleconsultation where suitable — and explains what they mean together with your symptoms.

A single abnormal hormone level rarely makes a diagnosis on its own. Some results need repeating; some only matter in a particular pattern (for example, high LH relative to FSH plus raised testosterone in suspected PCOS). The doctor will explain whether the next step is a repeat test, an ultrasound, a treatment trial, or a referral. Referral to an endocrinologist, gynaecologist, fertility specialist or urologist is usually considered when, for example, prolactin is persistently high, thyroid results suggest an overactive thyroid that needs specialist treatment, testosterone is clearly low on repeat testing, or periods have stopped without explanation. We can write the referral letter and include your results. Seek urgent care rather than a routine test for heavy vaginal bleeding with dizziness, severe abdominal pain (especially if you could be pregnant), a fast irregular heartbeat with chest pain or breathlessness, or sudden severe headache with visual loss.
