An essential part of heart health diagnostics (HHD) is the lactate dehydrogenase (LDH) test, which is a vital biomarker for assessing tissue integrity and cellular health. The body’s heart, liver, muscles, kidneys, brain, and blood cells are all home to the enzyme LDH. Because it facilitates the conversion of lactate to pyruvate, an essential step in metabolic processes, it plays a major role in the creation of energy. Heart attacks, liver problems, and some forms of cancer can all be detected and tracked with this test since elevated LDH levels can signify tissue damage or illness. In cases of severe infection or inflammation, as well as in the evaluation of hemolytic anemia, it is also utilized. By assessing LDH levels, medical professionals can learn important information about
