Zinc is a trace mineral involved in immune function, wound healing, hormone balance, and hundreds of enzyme reactions throughout the body. Because it's needed in so many processes, low zinc levels can produce a wide and sometimes confusing range of symptoms. Below are 10 of the most common signs of low zinc.

If you have been feeling more tired than usual, struggling with cravings, or noticing changes in your weight that are hard to explain, you may have come across the idea of testing your insulin levels. A fasting insulin blood test is one of the ways to look at how your body is managing sugar and energy, often before other signs become obvious. This article explains what a fasting insulin test actually measures, what your results can tell you, and what steps to consider next. If you would like to check your own levels, you can book a fasting insulin blood test through One Day Tests, with no GP referral needed and results usually available within 24 to 48 hours.

If you have recently had a cholesterol or lipid panel done and seen the term apolipoprotein B, or ApoB, on your results, you might be wondering what it actually means for your health. It is a marker that is becoming more widely tested because it often reveals more than standard cholesterol numbers alone, but a high result on its own can feel confusing without context. This article explains what apolipoprotein B does in the body, what a raised level suggests, and what practical steps you can take if your result comes back high. If you would like to check your own levels, you can book an apolipoprotein B blood test through One Day Tests, with no GP referral needed and results usually available within a day or two.

Noticing more hair on your pillow, in the shower drain, or on your hairbrush can be unsettling, especially when there is no obvious reason for it. One of the first questions many people ask is whether a simple blood test can explain what is going on. The good news is that blood tests are one of the most useful tools for understanding hair thinning, and they are commonly used by dermatologists to help identify underlying causes. This article explains what a blood test can and cannot tell you about hair thinning, which markers are most relevant, and what to do with your results. If you would like to start investigating your own hair health, you can book a female hair loss blood test with One Day Tests, with no GP referral needed and results usually available within a day or two.

A blood test can identify many common medical causes of hair loss, including iron deficiency, thyroid disorders, vitamin deficiencies, and hormonal imbalances. However, not every type of hair loss can be diagnosed through blood testing alone. Conditions such as pattern hair loss often require a clinical assessment because blood test results may be completely normal.

Fertility is closely linked to hormone balance. These hormones control ovulation, menstrual cycles, and egg quality which are all vital factors when trying to conceive. If conception isn’t happening as expected, fertility hormone testing can provide essential answers. A fertility hormone blood test measures key hormones that influence reproductive health in both women and men. It helps identify whether ovulation is occurring normally, if egg or sperm production is being affected, or if another hormonal imbalance might be making conception more difficult.

Many men looking to improve their energy levels, gym performance, mood, or sex drive want to know how they can boost their testosterone as quickly as possible. The reality is that there is no safe overnight method that dramatically increases testosterone naturally. While some products claim to provide rapid results, meaningful improvements in testosterone levels usually come from addressing the factors that suppress hormone production in the first place.

Low testosterone is a common health concern that affects men of all ages. While testosterone naturally declines over time, there are many other factors that can contribute to lower levels, including lifestyle habits, medical conditions, medications, and problems affecting the testes or hormone producing glands.

Testosterone is a prescribed medicine and must be used only as prescribed. Do not increase your dose, take an additional dose, or “dose ahead” to cover a period of travel unless this has been specifically discussed and agreed with your clinician.
