Healthy Lifestyle Blood Test

Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.

The primary iron storage protein. Ferritin reflects total body iron stores and is the first marker to drop in iron deficiency. However, ferritin also rises with inflammation, infection, and liver disease, which can mask true iron deficiency.

A protein produced by the liver in response to inflammation. CRP rises rapidly during infection, injury, or inflammatory conditions. It's a general marker — elevated CRP signals inflammation but doesn't pinpoint the source.

The ratio of albumin to globulin proteins in blood. A low A/G ratio may indicate overproduction of globulins (as in multiple myeloma or autoimmune disease) or underproduction of albumin (liver disease).

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels can lead to jaundice and indicate liver or bile duct problems.

Measures the combined amount of albumin and globulin proteins in your blood. These proteins are essential for fighting infections, blood clotting, and transporting substances throughout the body.

A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.

A liver enzyme sensitive to alcohol use and bile duct problems. GGT is often the first liver enzyme to rise when bile ducts are blocked. Combined with ALP, it helps determine whether elevated ALP is from liver or bone.

An enzyme found in the liver, bones, kidneys, and digestive system. Elevated ALP can indicate bile duct obstruction, liver disease, or bone disorders. It's normally higher in children and during pregnancy due to bone growth.

A waste product from normal muscle metabolism, filtered by the kidneys. Blood creatinine levels reflect kidney filtration capacity. Elevated levels may indicate impaired kidney function, dehydration, or excessive muscle breakdown.

An estimated measure of how well your kidneys filter waste from the blood. It's calculated from creatinine levels, age, sex, and race. eGFR is the primary marker used to stage chronic kidney disease.

A waste product from protein breakdown, processed by the liver and excreted by the kidneys. Elevated urea levels can indicate kidney dysfunction, dehydration, high-protein diet, or gastrointestinal bleeding.

Reflects your average blood sugar over the past 2–3 months by measuring the percentage of hemoglobin with attached glucose. HbA1c is the gold standard for diagnosing and monitoring diabetes, unaffected by daily fluctuations.

The most common type of fat in the body, stored for energy. Elevated triglycerides — often from excess sugar, alcohol, or calories — increase cardiovascular risk and can cause pancreatitis at very high levels.

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Often called 'bad' cholesterol, LDL deposits cholesterol in artery walls, contributing to plaque buildup and atherosclerosis. LDL is the primary target for cardiovascular risk reduction through diet, exercise, and medication.

Non-HDL cholesterol is the total cholesterol minus HDL cholesterol, representing all "bad" cholesterols. High levels can increase the risk of heart disease.

Often called 'good' cholesterol, HDL carries cholesterol away from arteries back to the liver for removal. Higher HDL levels are protective against heart disease. Exercise, healthy fats, and moderate alcohol intake can raise HDL.

The combined measure of all cholesterol in your blood, including HDL, LDL, and VLDL. While useful as an overview, the breakdown between HDL and LDL is more clinically meaningful for assessing cardiovascular risk.
