Lactate dehydrogenase (LDH) is an enzyme found in nearly all body tissues, including blood cells, heart, kidneys, lungs, liver, and muscles. When cells are damaged or destroyed, LDH is released into the bloodstream. Elevated LDH is a nonspecific marker that can indicate hemolytic anemia, liver disease, heart attack, muscle injury, some cancers (especially lymphoma), and severe infections. It is often used as a general indicator of tissue damage and to monitor treatment response in cancer patients. Because it is nonspecific, abnormal results are typically followed by more targeted testing.
General health testing provides a baseline snapshot of organ function, metabolism, and key biomarkers — useful for annual checkups, preventive care, and tracking changes over time.
Adults wanting a routine wellness baseline, anyone re-engaging with healthcare after a gap, and people tracking the impact of lifestyle or medication changes.

Your LDH (Lactate Dehydrogenase) results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–3 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
No fasting required. Avoid strenuous exercise for 24 hours before the test.
A LDH (Lactate Dehydrogenase) test costs $19.99 at TestWell — $25.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $120.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
