Metabolic and Kidney Tests
The Tests (11)
Kidney Function
Blood urea nitrogen (BUN), creatinine, estimated glomerular filtration rate (eGFR) and cystatin C together estimate how well the kidneys filter blood, used to screen, stage and monitor kidney disease.
Read the deep dive →Comprehensive Metabolic Panel
This 14-test blood panel adds liver enzymes, proteins and bilirubin to the basic panel, covering blood sugar, kidneys, electrolytes and liver in one draw.
Read the deep dive →Calcium
Measures total and ionized calcium in blood to check for high or low levels; albumin shifts can move the total without changing active calcium.
Read the deep dive →Urinalysis
Visual, dipstick and microscope examination of urine that can flag problems in the kidneys, urinary tract, liver and metabolism, often before symptoms appear.
Read the deep dive →Magnesium Test
Serum and red-blood-cell tests for magnesium, a cofactor in hundreds of reactions; a normal serum result can hide depleted body stores.
Read the deep dive →Microalbumin ACR
A urine test for small amounts of leaking albumin, often the earliest sign of kidney strain in diabetes or high blood pressure.
Read the deep dive →Basic Metabolic Panel
Eight blood chemistry measurements from one tube — glucose, calcium, electrolytes, blood urea nitrogen and creatinine — a quick snapshot of kidneys, fluids and blood sugar.
Read the deep dive →Uric Acid
Blood level of uric acid, the end product of purine breakdown, used to check gout and kidney-stone risk and studied as a cardiovascular marker.
Read the deep dive →Cystatin C
A blood protein made steadily by nearly every cell, used to estimate kidney filtration with far less influence from muscle mass than creatinine.
Read the deep dive →Ammonia
A blood test for ammonia, a protein-breakdown waste the liver clears, used to check confusion in liver disease; the sample needs careful, rapid handling.
Read the deep dive →Lactate
Measures blood lactate, which climbs when tissues are starved of oxygen; ordered in sepsis and shock, where its trend over time matters most.
Read the deep dive →Electrolytes, waste products and kidney filtration. These are the panels ordered most often, because they are the ones that change first when something is going wrong.
