How to browse
Search by abbreviation, full name, or common shorthand, then compare it with the range and related markers on the same page.
Liver, lipids, blood cells, iron studies, and kidney markers often make more sense when reviewed as a group.
If you are unsure where to start, the reading guide helps explain why one number rarely tells the whole story.
Start with common markers.
ALT is a liver-related blood test. A higher result may be associated with liver irritation, recent illness, medicines, exercise, or other factors. Educational only, not a diagnosis.
Ferritin reflects iron stores. A lower ferritin result may be associated with low iron stores, especially when symptoms like fatigue or hair shedding are also present. Educational only, not a diagnosis.
LDL is often called ‘bad’ cholesterol because higher levels may be associated with more plaque build-up risk over time. Clinicians still interpret it with the full lipid profile and overall risk picture.
TSH is a thyroid-related blood test. A result above or below the usual range may be associated with thyroid hormone patterns, medicines, pregnancy, or recent illness. Educational only, not a diagnosis.
HbA1c reflects average blood sugar over the last two to three months. A higher result may be associated with a longer-term glucose pattern above the usual range. Educational only, not a diagnosis.

Showing 41 indicators.
Albumin is a protein made by the liver that helps keep fluid in the bloodstream and transports important substances. A low or high result is usually interpreted with kidney tests, liver tests, hydration, and clinical context.
ALP is a blood test linked to the liver and bones. A higher ALP result may be associated with bile duct changes, bone turnover, growth, pregnancy, or other factors. Educational only, not a diagnosis.
ALT is a liver-related blood test. A higher result may be associated with liver irritation, recent illness, medicines, exercise, or other factors. Educational only, not a diagnosis.
AST is an enzyme measured in blood tests. A higher AST result may be associated with liver irritation, muscle injury, medicines, alcohol, or recent illness. Educational only, not a diagnosis.
Bilirubin is a waste pigment processed by the liver and cleared through bile. Doctors usually review bilirubin with the rest of the liver panel because a high or low result can have many possible explanations.
A calcium blood test usually measures total calcium — the calcium circulating in your blood, about half of which is attached to proteins such as albumin. Because albumin levels and several hormones affect the result, doctors usually interpret total calcium alongside albumin, symptoms, and sometimes a separate ionized calcium test.
Creatinine is used as part of kidney function assessment. A higher result may be associated with dehydration, muscle mass, medicines, or reduced kidney filtering. Educational only, not a diagnosis.
CRP is a general inflammation marker. A higher result may be associated with infection, inflammation, tissue injury, or other conditions, but it does not point to a single cause on its own.
eGFR is an estimate of kidney filtering based on blood creatinine and other factors. A lower eGFR may be associated with reduced kidney filtering, but trends and repeat results often matter most.
ESR, or erythrocyte sedimentation rate, is a non-specific marker that may reflect inflammation-related changes. Doctors usually interpret ESR with CRP, CBC results, symptoms, and the wider clinical picture.
Fasting glucose reflects blood sugar after not eating for several hours. A higher result may be associated with diabetes-related patterns, stress, illness, or medicines. Educational only, not a diagnosis.
Ferritin reflects iron stores. A lower ferritin result may be associated with low iron stores, especially when symptoms like fatigue or hair shedding are also present. Educational only, not a diagnosis.
Folate, also called vitamin B9, supports DNA production and red blood cell formation. Doctors usually interpret folate with vitamin B12 and blood-count markers rather than as a stand-alone result.
Free T4 is one of the main thyroid hormones circulating in the blood. Doctors usually interpret Free T4 together with TSH because the combination is more useful than either result alone.
GGT is a liver-related blood test. A higher result may be associated with bile duct irritation, alcohol use, medicines, or other liver patterns. Educational only, not a diagnosis.
HbA1c reflects average blood sugar over the last two to three months. A higher result may be associated with a longer-term glucose pattern above the usual range. Educational only, not a diagnosis.
Hematocrit measures the percentage of blood made up of red blood cells.
HDL is often called ‘good’ cholesterol because higher levels are generally seen as more protective. A lower HDL result may be associated with overall cardiovascular risk patterns. Educational only, not a diagnosis.
Hemoglobin is the oxygen-carrying protein inside red blood cells.
This pattern means the neutrophil share is higher even though the total white blood cell count stays in range. It may be associated with stress, infection recovery, medicines, or timing of the test. Educational only, not a diagnosis.
IgE is an antibody involved in allergic responses.
LDL is often called ‘bad’ cholesterol because higher levels may be associated with more plaque build-up risk over time. Clinicians still interpret it with the full lipid profile and overall risk picture.
MCV reflects the average size of red blood cells.
MPV measures the average size of platelets in your blood.
Platelets help blood clot when you have a cut or injury.
Potassium helps muscles, nerves, and the heart work normally. High or low potassium needs careful context because medicines, kidney function, fluid balance, and even sample handling can affect the result.
RBC measures the number of red blood cells in your blood.
RDW describes the variation in red blood cell size.
Serum iron measures the amount of iron circulating in your blood, carried by a protein called transferrin. Because this level can shift with recent meals, supplements, and the time of day, doctors usually interpret it together with ferritin, TIBC, and transferrin saturation rather than on its own.
Sodium helps regulate water balance, nerve signaling, and muscle function. Low or high sodium results are usually interpreted with symptoms, hydration, kidney function, and how quickly the change happened.
TIBC measures the blood’s capacity to bind iron. A higher result may be associated with lower available iron, but it is usually interpreted with ferritin and transferrin saturation. Educational only.
Total cholesterol combines several lipid measurements. A higher result may be associated with elevated LDL, higher HDL, or a broader lipid pattern, so clinicians rarely interpret it alone.
Total protein reflects the balance of albumin and globulins in the blood. The A/G ratio compares those two groups and can add context, but it is usually interpreted with the rest of the chemistry panel rather than on its own.
Transferrin saturation is part of an iron panel. A lower result may be associated with lower available iron, but clinicians usually compare it with ferritin, TIBC, and blood counts first.
Triglycerides are a type of blood fat. Higher levels may be associated with recent meals, alcohol, diabetes patterns, weight changes, medicines, or inherited lipid patterns. Educational only, not a diagnosis.
TSH is a thyroid-related blood test. A result above or below the usual range may be associated with thyroid hormone patterns, medicines, pregnancy, or recent illness. Educational only, not a diagnosis.
Urea (BUN) reflects how the body processes protein and removes waste.
Uric acid is a waste product from purine metabolism. A high or low result may reflect kidney handling, hydration, diet, medicines, and other clinical factors, so the number is usually reviewed in context.
Vitamin B12 supports red blood cells and nerve health. Doctors usually interpret the result with symptoms and blood-count markers because low or high values can have several possible explanations.
A low vitamin D blood test may be associated with reduced sun exposure, lower dietary intake, absorption issues, or other factors. Educational only, not a diagnosis.
WBC measures the number of white blood cells in your blood.
