Counts the particles that actually carry cholesterol into your artery walls. It reads risk more directly than LDL alone, which is why your doctor looks here first.

Picks up low-grade inflammation in your blood vessels — a signal that can rise quietly years before anything feels wrong.

Largely set by your genes, so once is enough. A high result often runs in families and changes how closely the rest of the panel is watched.

The cholesterol that builds up in artery walls over time. Read together with ApoB rather than on its own.

Carries cholesterol back to the liver for clearing. Higher is generally better, but only in the context of the full panel.

Blood fats that respond quickly to food, alcohol and sleep — which makes them one of the most actionable markers here.

The sum of everything cholesterol-carrying in your blood. Useful as context, rarely useful alone.

A simple ratio your doctor uses to sanity-check the picture the other markers paint.

A waste product from breaking down certain foods and drinks. Read alongside the rest of your panel, it hints at how your kidneys and metabolism are keeping up.

The main sugar your body runs on. A single reading is a snapshot; your doctor reads it next to HbA1c for the fuller picture.

Your average blood sugar over the past 2–3 months, so one meal can't skew it. One of the most useful markers for spotting risk early.

The hormone that moves sugar out of your blood and into your cells. It can drift high years before glucose does, which makes it worth watching.

Reflects your growth-hormone activity, which supports muscle, bone and repair. A healthy level means that system is ticking along as expected.

Places your IGF-1 against what's normal for your age and sex, so the number is read in the right context rather than on its own.

The main form of estrogen, which shapes your cycle, bone strength and mood. Levels shift naturally through the month and across life stages.

A pituitary hormone that helps run the menstrual cycle. Read with LH and estradiol, it helps your doctor place where you are in that rhythm.

Another pituitary signal in the cycle, working alongside FSH. The pattern between the two tells your doctor more than either one alone.

Supports the second half of your cycle and balances estrogen. Timing matters, so your doctor reads it against where you are in the month.

A protein that carries testosterone and estrogen in the blood. It changes how much hormone is actually free for your body to use.

The share of testosterone your body can use right now, supporting energy, libido and muscle. Read together with total testosterone.

All the testosterone in your blood, bound and free. Useful context, but your doctor pairs it with the free level to read it properly.

Your main stress hormone, steering energy, blood sugar and inflammation through the day. Levels naturally peak in the morning and taper by night.

An adrenal hormone that helps offset the effects of stress and is a building block for other hormones. Read together with cortisol.

Immune proteins that can mistakenly target the thyroid. When present, they help explain why thyroid levels might be drifting.

Another immune marker that can flag an autoimmune cause behind thyroid changes, so care is aimed at the right thing.

The active thyroid hormone that drives metabolism, energy and mood. Read alongside TSH and T4 for the full picture.

Your brain's message to the thyroid, and usually the first marker your doctor checks. It tends to move before the others do.

The main hormone your thyroid makes, later converted into the active T3. Read with TSH to see how the two are talking to each other.

A protein waste product your kidneys clear. Read with creatinine, it hints at how well filtering — and your hydration — is holding up.

Compares two waste markers to separate hydration and diet effects from how the kidneys themselves are working.

A steady waste product from muscle activity that the kidneys filter out. A reliable everyday read on kidney function.

An estimate of how much blood your kidneys clean each minute — the single number that best sums up kidney function.

An enzyme concentrated in liver cells. When it rises, it's usually the liver asking for a closer look.

An enzyme found in the liver and muscles. Read next to ALT, it helps your doctor tell where a change is coming from.

An enzyme tied to bile flow and liver function. A healthy level points to smooth drainage through the liver.

The main protein the liver makes, carrying hormones and nutrients around the body. A steady level is a good sign of liver health.

A waste product from old red blood cells that the liver clears. It shows how well that clean-up is running.

The combined albumin and globulin in your blood — a broad read on nutrition, fluid balance and liver output.

A family of blood proteins that includes your antibodies. Read with albumin, it rounds out the liver and immune picture.

A small class of white blood cell involved in allergic responses. The count shows how many you have on patrol.

The share of your white cells that are basophils — usually under 1%. A quick read on your allergic-response cells.

White cells that manage allergy-related inflammation and fight parasites. The count is one input into your immune picture.

The proportion of white cells that are eosinophils, normally a small slice. Read alongside the absolute count.

The white cells behind long-term immunity and your response to viruses. A core part of the immune read.

The share of white cells that are lymphocytes — typically 20–40%. Read with the count for the fuller story.

White cells that clear bacteria and tidy up damaged tissue. The count shows how many are in circulation.

The proportion of white cells that are monocytes, your body's clean-up crew. Read next to the absolute count.

Your most common white cell and first responder to infection. The count is a key line in the immune picture.

The share of white cells that are neutrophils, usually the majority. Read with the count to keep it in proportion.

The total of all your immune cells — a broad read on how your defences are stocked at the moment.

Combines platelets, neutrophils and lymphocytes into one number that hints at the overall inflammatory load.

Supports red blood cells, nerves and steady energy. A healthy level means your body has what it needs to keep those running.

Your stored iron, held ready for making red blood cells. It's often the first iron marker to move when stores run low.

Reads your iron stores against inflammation, so a high ferritin driven by inflammation isn't mistaken for plenty of iron.

Folate (vitamin B9) inside your red cells — a longer-term read on your folate status, important for DNA and red-cell formation.

An amino acid tied to your B12, folate and B6 levels. Healthy amounts suggest those vitamins are doing their job.

Feeds hemoglobin, the protein that carries oxygen. The right level supports everyday energy and focus.

Measures how much iron your transport proteins could carry — useful context for reading your iron level.

How much of that carrying capacity is actually filled with iron, so your tissues get the oxygen they need.

Magnesium inside your red cells, supporting muscle relaxation, heart rhythm and energy — a steadier read than serum magnesium.

Helps you absorb calcium, keep bones strong and support mood and immunity. A common gap worth knowing about.

Backs your immune defences, wound healing and sense of taste and smell. Healthy levels keep those steady.

Part of how your body keeps its acid–base balance. Healthy levels protect steady energy and organ function.

Supports bones, teeth and muscle contractions, and plays a role in nerve signals. Tightly controlled by the body.

An electrolyte that helps manage fluid balance and the right acidity in your blood.

Keeps heart rhythm, nerve signals and muscle contractions steady. Diet moves it, which makes it worth tracking.

Balances hydration, blood pressure and nerve signalling. One of the core electrolytes your doctor keeps an eye on.

The share of your blood made up of red cells — a core read on your oxygen-carrying capacity.

The protein inside red cells that ferries oxygen to your muscles and brain. Low levels can help explain fatigue.

The average concentration of hemoglobin packed into your red cells — one clue to the type of any anemia.

The average amount of hemoglobin per red cell. Read with MCV and MCHC to characterise your red cells.

The average size of your red cells, which helps point to a cause when a count looks off.

The average size of your platelets, the cells that help your blood clot. A supporting read on platelet health.

The cells that let your blood clot and stop bleeding. A healthy count means that system is well stocked.

How many oxygen-carrying red cells you have. The foundation of the whole blood picture.

How much your red cells vary in size. Read with the others, it helps your doctor read anemia more precisely.
