LDH, or lactate dehydrogenase, is an enzyme involved in the conversion of sugar to energy in the body's cells. There are different types of LDH, known as isoenzymes, which are found in specific parts of the body, such as the heart, liver, muscles, and kidneys.
Testing LDH isoenzymes can be useful for monitoring the health of certain organs or identifying the cause of specific symptoms. For example, after a heart attack, the LDH level in the blood will change, which can assist in diagnosis. It can also indicate liver disease, muscle damage, or other conditions.
An LDH test provides insight into the presence and extent of tissue damage in the body. By measuring the specific isoenzymes, doctors can determine which part of the body is affected and, in some cases, assess the severity of the condition.
A high level of LDH in the blood can indicate tissue damage somewhere in the body. Depending on which LDH isoenzymes are elevated, this might suggest issues such as heart attacks, liver disease, kidney disease, or muscle damage.
A low level of LDH is generally not considered problematic and often has no clinical significance. However, in rare cases, it might indicate low activity in certain parts of the body, depending on which isoenzyme is low.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
