This test measures lactate dehydrogenase (LDH) isoenzymes in a sample of your blood. It's a general test that can help find out if you have tissue damage from disease or injury. It can also help show which organs and other tissues are likely to be damaged.

Apr 15, 2022 · An LDH (lactate dehydrogenase) test measures the level of LDH in your blood or other body fluid to check for tissue damage. Healthcare providers order LDH tests to help diagnose and monitor several different conditions.

May 1, 2023 · Lactate dehydrogenase (LDH) is an important enzyme of the anaerobic metabolic pathway. It belongs to the class of oxidoreductases, with an enzyme commission number EC 1.1.1.27. The function of the enzyme is to catalyze the reversible conversion of lactate to pyruvate with the reduction of NAD+ to NADH and vice versa.[1]

Jan 13, 2021 · High lactate dehydrogenase (LDH) is your body’s alarm bell: it signals tissue damage. LDH is an unspecific cue, as tissue damage can be due to many different conditions, including infections, liver, heart, kidney and muscle disease, anemia, and cancer.

What does it mean if your LD 2 (or LDH-2) result is too low? LDH deficiency affects how the body breaks down sugar for use as energy in cells, particularly muscle cells. It’s very rare for a person to have low LDH levels.

LDH-2 is usually the predominant form in the serum. An LDH-1 level higher than the LDH-2 level (a "flipped pattern") suggests myocardial infarction (damage to heart tissues releases heart LDH, which is rich in LDH-1, into the bloodstream).

Feb 10, 2025 · What Is a Lactate Dehydrogenase (LDH) Blood Test? LDH is an enzyme that turns sugar into energy. The LDH test tells you how much LDH is in your blood or other body fluid.

Discover the significance of lactate dehydrogenase levels, the LDH blood test process, and what elevated or low LDH levels mean for your health. Learn about causes, normal ranges, and diagnostic insights.

Nov 2, 2024 · Lactate dehydrogenase (LDH), or lactic dehydrogenase, is a critical enzyme found in various cells throughout the human body. There are several LDH isoforms; the serum LDH measures the total. There are five main LDH isoforms, designated as LDH-1, LDH-2, LDH-3, LDH-4, and LDH-5.

Feb 28, 2023 · The LDH test helps determine the location of tissue damage. LDH exists in five forms, which differ slightly in structure. LDH-1 is found primarily in heart muscle and red blood cells. LDH-2 is concentrated in white blood cells. LDH-3 is highest in the lung. LDH-4 is highest in the kidney, placenta, and pancreas.
