Bloodwork, explained.
With your life in mind.

Measures the overall amount of cholesterol in your blood.

Measures a type of fat your body uses to store energy.

Measures cholesterol carried by HDL particles, which help move it back to your liver.

Estimates cholesterol carried by LDL particles, one part of assessing heart health.

Estimates cholesterol carried by particles that also transport blood fats.

Calculates the cholesterol left after subtracting HDL from the total.

Compares total cholesterol with HDL as another way to view the results.

Measures small amounts of a protein that rises with inflammation; it does not show the cause.

Measures a substance made as your body processes a building block of protein.

Measures an enzyme found in many tissues; a result alone cannot show where a problem is.

Measures an enzyme used alongside other tests to look at the liver and bile ducts.

Measures a waste product made as your body breaks down substances called purines.

Measures the signal that tells your thyroid how much hormone to make.

Measures the total amount of one of your main thyroid hormones.

Helps assess the proteins that carry thyroid hormones; it is not a T3 hormone level.

Uses other test results to estimate the amount of available T4 thyroid hormone.

Measures the total amount of an active thyroid hormone.

Measures T4 thyroid hormone that is not attached to carrier proteins.

Measures an inactive form of thyroid hormone. Included in the panel, but not a test of weight-loss or GLP-1 response.

Measures T3 thyroid hormone that is not attached to carrier proteins.

Looks for immune proteins that can react with part of your thyroid.

Looks for immune proteins that can react with a protein made by your thyroid.

Reflects your average blood sugar over about the past three months.

Measures total testosterone, a hormone involved in muscle, bone and sexual health.

Measures a hormone made mainly by the adrenal glands, which sit above your kidneys.

Measures a form of estrogen, involved in reproductive and bone health.

Measures a hormone involved in the menstrual cycle and pregnancy.

Measures a hormone that helps regulate egg development and sperm production.

Measures a hormone involved in ovulation and testosterone production.

Measures a protein that carries sex hormones in your blood.

Translates your A1c result into an estimated average blood sugar number.

Measures the hormone that helps move blood sugar into cells, after fasting.

Measures the main form of vitamin D used to check your vitamin D level.

Measures an iron-storage protein; it helps assess iron stores and can also rise with inflammation.

Measures iron circulating in your blood at the time of the draw.

Measures how much iron your blood's carrier proteins can hold.

Measures magnesium inside red blood cells.

Measures zinc inside red blood cells.

Measures a substance your body uses to help protect cells from damage.

Measures how much room is left on your blood's iron-carrying proteins.

Shows what percentage of your blood's iron-carrying capacity is being used.

Measures an enzyme that helps protect red blood cells from damage.

Compares albumin and globulin, two main groups of proteins in your blood.

Measures your blood sugar after fasting, at the time of your blood draw.

Measures a waste product from protein breakdown that your kidneys remove.

Measures a waste product from your muscles that your kidneys filter out.

Estimates how well your kidneys filter your blood.

Measures a mineral that helps balance fluids and supports nerves and muscles.

Measures a mineral involved in heart rhythm, nerves and muscle function.

Measures a mineral that helps keep your body's fluids and acidity in balance.

Mostly measures bicarbonate, which helps keep your blood's acidity balanced.

Measures calcium in your blood, a mineral used by bones, nerves and muscles.

Measures the combined amount of major proteins in your blood.

Measures a liver-made protein that carries substances and helps keep fluid in your blood vessels.

Measures a group of blood proteins involved in transport and immune protection.

Measures a substance made when red blood cells break down; your liver helps clear it.

Measures a protein that helps chemical reactions, found mainly in your liver and bones.

Measures an enzyme found in your liver, muscles and other tissues.

Measures an enzyme found mainly in your liver cells.

Compares two waste products to add context to kidney-related results.

Counts the white blood cells that help your body fight infections.

Counts the red blood cells that carry oxygen around your body.

Measures the oxygen-carrying protein in your red blood cells.

Shows how much of your blood is made up of red blood cells.

Shows the average size of your red blood cells.

Shows how much your red blood cells vary in size.

Counts the small blood cells that help stop bleeding.

Shows the average amount of oxygen-carrying protein in each red blood cell.

Shows how concentrated that oxygen-carrying protein is inside red blood cells.

Shows the share of white blood cells that are neutrophils, one type of infection-fighting cell.

Shows the share of white blood cells involved in immune protection, including making antibodies.

Shows the share of white blood cells that help clear germs and damaged cells.

Shows the share of white blood cells involved in allergic responses and fighting some parasites.

Shows the share of white blood cells involved in allergic and inflammatory responses.

Counts neutrophils in a set amount of blood, rather than as a percentage.

Counts lymphocytes in a set amount of blood, rather than as a percentage.

Counts monocytes in a set amount of blood, rather than as a percentage.

Counts eosinophils in a set amount of blood, rather than as a percentage.

Counts basophils in a set amount of blood, rather than as a percentage.

Measures young white blood cells that have entered your bloodstream.
