How Much Does a Metabolic Panel Cost in 2026? BMP vs. CMP Price Guide

Metabolic panel blood tests are among the most frequently ordered lab tests in outpatient medicine — ordered at virtually every annual physical, urgent care visit, and hospital admission. The two main types — the basic metabolic panel (BMP) and the comprehensive metabolic panel (CMP) — differ in what they measure and by approximately $10–$50 in cash price at independent labs. At hospital outpatient facilities, the same panels can cost 5–10x more due to facility fees. Understanding the difference between BMP and CMP, and knowing where to get tested, is how you avoid overpaying.

BMP vs. CMP — What Is the Difference?

The choice between a basic and comprehensive metabolic panel comes down to what clinical question needs to be answered. The BMP focuses on electrolyte balance, kidney function, and blood sugar. The CMP adds six liver function tests, providing a broader picture of metabolic health in a single draw.

BMP (Basic Metabolic Panel) — 8 Tests

1. Glucose — blood sugar level
2. Calcium — bone, nerve, and muscle function
3. Sodium — fluid balance and nerve function
4. Potassium — heart rhythm and muscle function
5. Bicarbonate (CO2) — acid-base balance
6. Chloride — electrolyte balance
7. BUN (blood urea nitrogen) — kidney function
8. Creatinine — kidney function

When ordered: When the clinical question is primarily electrolyte balance, kidney function, and blood sugar. Most ER visits and hospital admissions order a BMP as the initial metabolic screen.

CMP (Comprehensive Metabolic Panel) — 14 Tests

The CMP includes all 8 BMP tests plus six additional liver function markers:

9. Total protein
10. Albumin
11. Total bilirubin
12. ALP (alkaline phosphatase)
13. AST (aspartate aminotransferase)
14. ALT (alanine aminotransferase)

The additional 6 tests assess liver function. When ordered: Annual physicals, medication monitoring (especially statins and other drugs that affect the liver), evaluation of jaundice or abdominal symptoms, and baseline liver function before starting medications.

Metabolic Panel Cost by Setting (2026)

Test	Independent Lab (cash)	Hospital Outpatient	Notes
Basic Metabolic Panel (BMP)	$15–$40	$100–$250	8 values: electrolytes + kidney + glucose
Comprehensive Metabolic Panel (CMP)	$20–$50	$150–$350	14 values: adds liver function
Renal Panel (kidney function only)	$15–$35	$80–$200	BUN, creatinine, eGFR, electrolytes
Hepatic Panel (liver function only)	$15–$35	$100–$250	ALT, AST, ALP, bilirubin, albumin
Electrolyte Panel	$10–$25	$80–$180	Sodium, potassium, chloride, CO2 only

What Each Metabolic Panel Value Means

Knowing what each marker measures helps you understand your results and ask better questions at your next appointment.

Glucose

Fasting glucose above 100 mg/dL is classified as prediabetes; above 126 mg/dL meets the diagnostic threshold for diabetes. The metabolic panel glucose can also screen for hypoglycemia in symptomatic patients — low fasting glucose below 70 mg/dL warrants further evaluation.

Kidney Markers — BUN and Creatinine

Elevated BUN (blood urea nitrogen) and creatinine indicate impaired kidney filtration, which may reflect acute kidney injury or chronic kidney disease. The BUN-to-creatinine ratio is also diagnostically useful: a ratio above 20 suggests pre-renal causes such as dehydration or gastrointestinal bleeding rather than intrinsic kidney disease. Many labs also report eGFR (estimated glomerular filtration rate), calculated from creatinine plus age, sex, and race, which directly estimates kidney function.

Electrolytes — Sodium, Potassium, Bicarbonate, Chloride

Electrolyte abnormalities can be clinically significant even at modest deviations from normal. Low potassium (hypokalemia) below 3.5 mEq/L can cause dangerous cardiac arrhythmias, particularly in patients taking digoxin or other antiarrhythmic drugs. Low sodium (hyponatremia) below 135 mEq/L can cause confusion, falls, and in severe cases, seizures and cerebral edema. Bicarbonate reflects acid-base balance — a low bicarbonate may indicate metabolic acidosis from causes including diabetic ketoacidosis, lactic acidosis, or severe diarrhea.

Liver Markers — ALT, AST, ALP, Bilirubin (CMP Only)

The liver enzymes included in the CMP are the primary tools for detecting hepatocellular damage and cholestatic disease. Elevated ALT and AST indicate hepatocellular injury — common causes include non-alcoholic fatty liver disease (NAFLD), viral hepatitis, alcohol-related liver disease, and drug-induced liver injury (statins, acetaminophen, antibiotics). ALT is more liver-specific than AST; an AST-to-ALT ratio greater than 2:1 is characteristic of alcoholic hepatitis. Elevated ALP combined with elevated bilirubin suggests cholestatic disease — causes include bile duct obstruction (gallstones, cholangiocarcinoma), primary biliary cholangitis, and primary sclerosing cholangitis.

What Does Insurance Cover for Metabolic Panels?

Routine metabolic panels ordered as part of a preventive annual visit are covered 100% under ACA preventive care guidelines — no cost-sharing applies when the panel is the only reason for the visit. However, if the panel is ordered during a diagnostic visit (for a specific symptom such as fatigue, nausea, or elevated blood pressure), cost-sharing in the form of copays and deductible applies. The distinction between preventive and diagnostic billing is one of the most common sources of unexpected medical bills for patients who assumed their annual physical labs would be free.

Hospital facility fees are the most common surprise cost associated with metabolic panels. An outpatient metabolic panel ordered through a hospital-affiliated lab adds $75–$300 in facility charges that are separate from and in addition to the laboratory fee itself. Patients who receive lab orders from a hospital-employed physician and fill those orders at a hospital-affiliated lab collection site may be billed as hospital outpatient even if they never set foot in a hospital building.

When Is a Metabolic Panel Ordered?

Metabolic panels are ordered across a wide range of clinical contexts:

• Annual physical (CMP): Screening for diabetes, kidney disease, liver disease, and electrolyte abnormalities as part of routine preventive care.
• Pre-surgical workup (BMP): Anesthesiologists require baseline electrolyte and kidney function data before elective procedures.
• ER triage (BMP): Nearly every emergency department patient receives a BMP as part of the initial diagnostic evaluation.
• Monitoring patients on diuretics, ACE inhibitors, or ARBs (BMP/renal panel): These medications affect electrolyte levels and kidney function and require periodic monitoring.
• Monitoring patients on statins, metformin, or hepatotoxic drugs (CMP): Statins and some other medications can cause liver enzyme elevations and require periodic liver function monitoring.
• Evaluating symptoms of fatigue, weakness, nausea, or abdominal pain (CMP): A CMP is often the first-line workup for non-specific symptoms that could reflect metabolic, renal, or hepatic pathology.

How to Lower Your Metabolic Panel Cost

1. Order at a direct-to-consumer lab. Quest Diagnostics charges $19–$30 for a CMP as of 2026, no physician order required in most states. LabCorp offers comparable pricing. Using a direct-to-consumer lab for non-urgent routine draws eliminates the physician office visit copay as well.
2. Confirm the test is covered as preventive at your annual visit. When the metabolic panel is ordered solely as part of your yearly wellness exam and no other diagnoses are being evaluated at the same visit, it qualifies as preventive care and is covered 100% under ACA-compliant plans. If your physician also addresses a chronic condition at the same visit, the visit may be billed as diagnostic, triggering cost-sharing.
3. Avoid hospital outpatient for routine metabolic panels. Independent commercial labs (Quest, LabCorp, independent regional labs) charge $15–$50 for a metabolic panel. Hospital outpatient labs charge $100–$350 for the same test. Save $100–$300 by using an independent lab for non-urgent routine draws.
4. Know whether you need a BMP or CMP. If your clinical question is kidney function and electrolytes only — for instance, monitoring while on a diuretic — a BMP or renal panel is sufficient. The CMP adds liver function tests that may not be needed in every monitoring context. Ask your physician which panel is clinically necessary for your situation.
5. Use your FSA or HSA. Metabolic panels ordered with or without a physician order are FSA/HSA eligible expenses. Using pre-tax dollars to pay for lab tests reduces the effective out-of-pocket cost by your marginal tax rate.

The Bottom Line

A basic metabolic panel costs $15–$40 at an independent lab and $100–$250 at a hospital. A CMP — which adds liver function — costs $20–$50 at an independent lab. At these prices, ordering a CMP instead of a BMP at an independent lab makes economic sense when your physician wants a complete metabolic picture. For routine, non-urgent testing, avoid hospital outpatient labs — the facility fee alone adds $75–$300 to any outpatient lab order. Insurance covers metabolic panels ordered at preventive visits at 100% under ACA; expect cost-sharing when ordered at diagnostic visits for specific symptoms. When in doubt, confirm with your insurer how the visit will be coded before you get your labs drawn.
