Liver Function Panel

Both cover liver enzymes. The CMP bundles 6 metabolic tests (glucose, kidney, electrolytes) alongside the liver markers — only ~$5 more. Order the standalone Liver Function Panel only if you specifically don't need kidney/electrolyte readings.

TestWell charges $19.99 — vs $29 at Quest Direct and $80-$180 at hospital outpatient labs. Quest or Labcorp lab, same-day or next-day results.

Yes — 8-12 hours of fasting (water only) for the most accurate ALT/AST/ALP readings. Fasting also makes results comparable across multiple draws.

Mildly elevated ALT/AST (1-3× normal): often fatty liver, alcohol, or medication. >5× normal: acute hepatitis, drug-induced injury, autoimmune liver disease — see a clinician promptly. Pair with Hepatitis Panel to rule out viral causes.

Annually if you take statins or have NAFLD risk factors. Every 3-6 months when starting a new liver-metabolized medication.

Liver enzymes and bilirubin require a venous blood sample, so at-home liver kits are limited to a few markers and are not what clinicians use. TestWell gives you the full 7-marker panel (CPT 80076) without a doctor's visit: you order online from home, walk into any Quest or Labcorp patient service center when it suits you — no appointment or doctor's visit needed — and results post to your TestWell account in 1–3 business days. No fasting is needed.

A hepatic panel (liver function test, LFT, liver profile) is one blood draw that checks seven markers: the enzymes ALT, AST and ALP, which rise when liver cells or bile ducts are irritated; GGT; bilirubin, the bile pigment behind jaundice; and albumin and total protein, which show how well the liver is making proteins. Together they screen for hepatitis, fatty liver, bile-duct problems and medication side effects. $19.99 at Quest or Labcorp, no fasting.

Ordered directly, a Liver Function Panel lists at $119.00 at Quest Health (Quest Diagnostics' own site) and $79.00 at Labcorp OnDemand (prices checked September 2026). TestWell orders the same test at the same Quest or Labcorp patient service centers for $19.99 — $25.99 all-in with the $6 per-order lab processing fee — paid out of pocket at checkout with no insurance, doctor's visit or draw fee; HSA and FSA cards are accepted.

Liver Function Panel results are typically ready in 1–3 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.

Alcohol, exercise, dehydration and common medications can change a Liver Function Panel result without anything being wrong. Alcohol can raise AST — abstain 24–72 hours before a liver panel. Exercise can raise AST — rest 48 hours before a liver panel. Dehydration can raise Albumin — hydrate normally. Common medications can raise AST — continue; report muscle pain to the prescriber. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
