I think you should discuss your tumor maker results and the LDH . :mad2: Sorry for the rant. LDL should be lower than this for those at risk of heart attacks or stroke. Metabolic changes in rapidly dividing cancer cells are closely associated with increased uptake of glucose and abnormal activity of lactate dehydrogenase (LDH), which regulates the processing of glucose to lactic acid. High levels of LDH can indicate a number of medical conditions such as tissue damage (due to trauma or disease), hemolytic anemia (an abnormal breakdown of red blood cells), liver disease, encephalitis , kidney failure, a recent heart attack, and some types of cancer. High values A high reticulocyte count may mean more red blood cells are being made by the bone marrow. Conditions that can cause increased LDH in the blood include liver disease, heart attack, anemia, muscle trauma, bone fractures, cancers, and infections such as meningitis, encephalitis, and HIV. . But, evaluating or measuring the levels of LDH can help in treating many diseases like Ewing's sarcoma, testicular cancer, non-Hodgkin's lymphoma and other types of leukemia. :frown: LDH levels become elevated when cells and tissues are damaged, and are particularly high during active tumor progression into .

LDH is found in many of the body's tissues and organs, including the muscles, liver, heart, pancreas, kidneys, brain and blood cells. So, the combination of an abnormal MRI and increased LDH-3 can mean that a sarcoma is present. Itoyana (2001) has reported the clinical significance of Cytogenetic analysis in adult T-cell leukemia/lymphoma along with elevated levels of serum LDH as prognostic markers, in patients with survival period of less than six months. Subsequently, question is, does high LDH mean cancer? Lactate dehydrogenase (LDH) levels sometimes act as a good index of response to the treatment of malignant lymphoma. Serum lactate can also be elevated due to hypermetabolism from aggressive lymphoma. It has long been known that many human cancers have higher LDH levels than normal tissues [1]. A higher than normal LDH level may also mean treatment for cancer is not working. Does high LDH mean cancer? I mean I feel bad enough for not noticing the LDH.

The degree of increase in LDH usually suggests which health issue a doctor considers. When your LDH rises, it means that tissues may have been damaged or are diseased. Haptoglobin, if low with an elevated LDH, is very suggestive of hemolytic anemia. This also applies to samples with gel separators since the Buffy coat of white cells and platelets (which has a high LDH) is abov. But it is better to investigate the cause of high HDL.

Severe elevations of the total LDH activity in serum (up to 50 times the upper reference limit) have been observed in the megaloblastic anemias. What does a high LDH level in the lung mean? The prognostic response of various blood cancer patients, who had elevated serum LDH levels, is shown in Table 5. Tumor markers are commonly used in cancer care to monitor treatment response or for recurrence of cancer, but they must be part of a bigger picture, including physical exam, patient symptoms and radiology studies. There is evidence that high level of serum lactate dehydrogenase (LDH) is associated with poorer overall survival in several malignancies, but its link to cancer-specific survival is unclear. After a negative result, you will have a PSA test every three to six months. LDH is an enzyme found in almost every cell of your body, including your blood, muscles, brain, kidneys, and pancreas.
