Elevated Alkaline phosphatase (ALP) result

Hi All,

I've just got my blood test results back and my Alkaline phosphatase (ALP) level has increased since last year.

ALP Test Nov 08: 90 (all of my blood tests have been 90 and nothing under/over consistently for my 23 years of life)
ALP Test Sep 09: 93

Should I be as worried as I feel? All other liver tests are normal.

I've been suffering with abdominal pain for 8 months, I'm having a colonoscopy and endoscopy next week, but I've been to see a specialist who says he is 95% sure its Irratable bowel and hes only putting me in for the tests to rule things out.

I've had Ultrasounds of my upper abdomen including the Liver back in march, Everything was normal, including Gallbladder, pancreas, stomach, bile ducts etc...

Also, kidney function and ESR tests are normal.

Should I be panicing about an increase of 3 on my Alkaline phosphatase (ALP) levels?

Please help, I suffer from anxiety and this is really worrying me. The doctor said its ntohing to worry about, but I'll go back to have it checked again in 6 months time.

Im taking omeprazole for acid reflux.

Thank you all so much for reading, please help!
