Perimenopause Health Check Complete

Perimenopause can start years before your last period, and it rarely shows up as one clear symptom. Irregular cycles, hot flushes, disrupted sleep, brain fog and low mood can all be part of it - but thyroid problems and iron deficiency produce many of the same symptoms, and both are common at this age. This panel checks your hormones alongside thyroid and iron in the same test, so a normal hormone result still leaves you with useful answers rather than a dead end. It also adds the bone and cardiovascular markers that shift as oestrogen falls, often well before any symptom appears.

Based on your results, our health professionals provide educational context to help you understand where you sit and what it might mean, so you can have an informed conversation with your doctor. This is especially useful if you're considering hormone replacement therapy - i-screen doesn't prescribe HRT, but these results give you and your prescriber a clear baseline to start from.
If you use hormonal contraception, read our guide on hormonal contraception and hormone testing first, since your method can affect how your results should be read.
What's included
This blood test measures the levels of key hormones that change with peri-menopause. This menopause blood test can also be used to monitor Hormone Replacement Therapy.
Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.
This simple iron test measures how much iron you have in your blood, as well as the amount of iron you have stored in your body. Iron levels are relevant to energy, blood cell health and overall wellbeing.
The full blood count measures red cells, white cells and platelets — foundational markers included in most health assessments. It is actually a group of tests that examine different parts of the blood. Results from the following tests provide the broadest picture of your health.
This panel measures the key nutrients and hormones essential for bone health, including Parathyroid Hormone (PTH) for calcium regulation, Vitamin D for bone density, Calcium for bone strength, Phosphate for bone formation, and Magnesium for bone structure and muscle function.
Insulin resistance can lead to difficulty losing weight, distinct abdominal fat, fatigue, bloating and sugar cravings. Identifying insulin resistance early and committing to lifestyle changes can ultimately help the progression to diabetes.
Lipids and cholesterol are fat-like substances in your blood. Some are necessary for good health, but when you have a high level of cholesterol in your blood, a lot of it ends up being deposited in the walls of your arteries and other vital organs. Lifestyle choices including diet, exercise and alcohol intake can all influence cholesterol levels and your risk of developing heart disease.
The apo B/apo A1 ratio indicates the cholesterol balance between potentially atherogenic (bad) and anti-atherogenic (good) particles.
Vitamin B12 is an essential vitamin found in meat products and certain algae such as seaweed. It helps maintain healthy nerve cells and red blood cells and is also needed to make DNA, the genetic material in all cells. Symptoms of a Vitamin B12 deficiency can include fatigue, anaemia and poor balance. Check out our Vitamin B12 Check for more information.
hsCRP is a highly sensitive marker of systemic inflammation. Even small elevations in hs-CRP can signal ongoing immune activity and are linked to higher cardiovascular and metabolic risk.
