How to Prepare for the ALP Blood Test?

Also let the doctor know if you are pregnant as it can increase the ALP levels in your blood.

It may also indicate kidney cancer tumors, malnutrition, problems with the pancreas, or an infection.

If you have higher than normal alkaline phosphatase levels, it may indicate the following liver or gallbladder problems.

  • Liver cancer

  • Certain types of hepatitis

A high level of ALP is also associated with the following bone problems.

  • Rickets

  • Paget’s disease

In rare cases, a high level of ALP may indicate heart failure, mononucleosis, bacterial infection, or certain cancers like kidney cancer.

If you have lower than normal alkaline phosphatase levels, it may indicate protein deficiency, Wilson’s disease, malnutrition, and vitamins deficiency. A low ALP can also be an effect of hypophosphatemia, a rare condition that causes fragile bones which can easily fracture. If the ALP levels are abnormal, your doctor may order more tests such as isoenzyme tests [6] to make a diagnosis and offer treatment.
