My son has an elevated Alk Phos on two consecutive tests, the first was 3954, the second was 3409. He had blood work done due to a high fever (104-105) and he became slightly dehydrated. The cause of the fever was never determined, but was assumed to be a virus. He had additional blood work that was off, but not as bad. He also has tiny dark red bumps appearing on his face and chin , which he recently started getting since the illness . It doesn t appear to be a rash - it s just bumps under the skin. He is 21 months old. He routinely is fatigued and some times just has no appetite , and is routinely constipated, despite a healthy diet. He also has a small bump on his neck of unknown origin. He typically (once or twice a month) will run low grade fevers do not require medication and only last a day. He was not on any medication other than motrin when his blood was tested. He will be retested in the coming weeks on his blood work. The doctor wanted to perform a CT scan , but my wife did not agree with injecting him with radiation at the time. Any guesses as to these symptoms. The doctor did mention cancer as a possibility.
