Low LDH level in the blood

What is low total LDH level in the blood called?

  • LDH low

What is the normal LDH level in the blood?

If you need to know which are the LDH reference ranges or you require more information about the role of LDH in the blood you can visit: Normal LDH level in the blood

What does a low total LDH level in the blood mean?

A low level of LDH (lactate dehydrogenase) in the blood is not common, it is not clinically significant and it is not usually a matter for concern.

Sometimes, LDH is used to monitor a cancer treatment and if LDH values decrease, it is a positive sign of the treatment.

LDH blood values are usually given in UI/l but sometimes you can see these values in µkat/L following the International System of Units (SI). In case your values are in µkat/L you can convert them using this tool:

UI/l

A low LDH blood level means:

  • Moderate LDH decrease (< 130 UI/l in adults):

    LDH level is below the normal range and it may be due to an excessive vitamin C intake or due to a drug interference.

    However, there are some people with a genetic mutation with a low permanent LDH level in the blood. There are two genetic disorders:

    • Lactate dehydrogenase-A deficiency (glycogen storage disease XI). People with this disorder suffer from fatigue, cramps and muscle pain doing exercise.
    • Lactate dehydrogenase-B deficiency: People with this disorder usually have no symptoms.

Which factors can reduce the LDH level in the blood?

Some particular health situation or drugs may reduce your LDH level in the blood:

  • Vitamin C excess intake
  • Drugs
    • Antiasthmatic drugs
      • Theophylline
    • Anticoagulants
      • Oxalates
    • Salicylates

Which diseases can reduce your LDH level in the blood?

The following diseases can explain a LDH level in the blood lower than normal:

  • Lactate dehydrogenase-A deficiency (glycogen storage disease XI)
  • Lactate dehydrogenase-B deficiency

What can I do to increase the LDH level in the blood?

A low level of LDH in the blood may be due to an excessive intake of vitamin C. For that reason, you may reduce the vitamin C intake if this is the cause. There are rich in vitamin C and you should reduce the intake of oranges, tangerines, peppers, broccoli, strawberries, melon or kiwis.

Where can I find more information about LDH level in the blood?

Which values are considered a low LDH level in the blood?

The following values are considered to be above the normal range:

IMPORTANT: These levels are expressed in UI/l. They are an example of a healthy man of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
