NGAL rises are seen in cancer-patients

As mentioned in the MedicoInvestor Presentation NGAL for Dummies, Inflammation and cancer will often result in higher NGAL values, than what is present in normal healthy individuals. NGAL is not exclusively produced by the Kidneys, but also from whote blood cells, and other types of tissue.
