    WHAT IS THE NORMAL RANGE FOR KIDNEY FUNCTION TEST?

    Kidney function tests are commonly used to check how well the kidneys are working, but receiving a result can be confusing if you are unsure what is considered normal. Many people are told their kidney function is slightly reduced or borderline without a clear explanation of what the numbers mean or whether there is cause for concern. Understanding the normal ranges helps put results into context and explains why factors such as age, hydration and overall health are taken into account.

    WHAT DOES SODIUM LEVEL IN A BLOOD TEST MEAN?

    Sodium is an essential electrolyte that helps regulate fluid balance, nerve signals, and muscle function in the body. When you have a sodium blood test, it measures how much sodium is present in your bloodstream at that moment. Even small changes in sodium levels can affect how the body functions, which is why this test is commonly used in both routine checks and symptom investigation.

    WHAT DOES IT MEAN WHEN YOUR IGF 1 IS HIGH?

    IGF 1, or insulin-like growth factor 1, is a hormone that reflects how much growth hormone your body is producing over time. When IGF 1 levels are high, it usually means that growth hormone activity is increased.

    WHAT DO OESTRADIOL LEVELS TELL YOU?

    Oestradiol is the main and most active form of oestrogen in the body. Measuring oestradiol levels can provide valuable insight into hormone balance, reproductive health, and how the body is functioning at different life stages. Because oestradiol affects many systems, including the reproductive organs, bones, brain, and cardiovascular system, changes in its levels can help explain a wide range of symptoms.

    DOES OESTRADIOL CAUSE WEIGHT GAIN?

    Oestradiol is one of the main forms of oestrogen in the body and plays a central role in female health. It affects the menstrual cycle, fertility, bone strength, mood, and metabolism. Because it influences how the body stores fat and uses energy, many people wonder whether changes in oestradiol levels can lead to weight gain.

    WHAT ARE NORMAL OESTRADIOL LEVELS BY AGE?

    Oestradiol is the main and most active form of oestrogen in the body. Its levels change naturally throughout life, from childhood and puberty through reproductive years and into menopause. Because of this, what is considered a normal oestradiol level depends heavily on age, life stage, and in women, menstrual cycle timing.

    WHAT IS A NORMAL TESTOSTERONE LEVEL IN A CHILD?

    Testosterone is often thought of as an adult male hormone, but it is also present in children at different stages of development. Parents and carers may become concerned if a blood test has been suggested or if there are questions around early or delayed puberty. Understanding what is considered normal at different ages helps put test results into context and avoids unnecessary worry.

    WILL TESTOSTERONE SHOW UP IN A BLOOD TEST?

    If you are experiencing symptoms that may be linked to hormone changes, it is natural to wonder whether testosterone can be accurately detected through blood testing. Many people are unsure how testosterone is measured, what the results actually show, and whether a single test is enough to give a clear picture of hormone health. Understanding how testosterone appears in blood results helps explain why testing is the first step before any diagnosis or treatment is considered.

    WILL MY GP GIVE ME A TESTOSTERONE TEST?

    Many men who experience symptoms such as low energy, reduced libido, mood changes, or difficulty building muscle begin to wonder whether low testosterone could be the cause. A common first question is whether a GP will arrange a testosterone blood test through the NHS, or whether private testing is required. Understanding how testosterone testing works in primary care, what criteria GPs use, and what options are available if testing is declined can help you decide the best next step.
