He has undergone many tests like endoscopy, Complete Blood count, Thyroid, stool test for blood loss, blood sugar test and ultrasonography. All results are normal.Today he underwent Liver function test (2 of the parameters are above reference range). Results are as follows (reference range given in bracket):S. BIluribin - 1.5 (0 - 1)D. Biluribin - 0.3 (0 - 0.2)SGOT - 15 (6 - 40)SGPT - 17 (8 - 37)S. Alkali - 102 (36 - 140)Total protein - 8.3 (6 - 8.5)S. Albumin - 4.4 (3.5 - 5)Globulin - 3.9 (2.5 - 5)AG Ratio - 1.1 (1 - 1.4)S. Biluribin and D. Biluribin are slightly above reference range. What does it indicate. Please advise. Are there any more tests needed?Thanks in advance.

### output:

Hello. As you say S. Bilirrubin and D. Bilrrubin are slightly above reference range. The most common causes of increased bilirubin levels are liver, vesicle or pancreas diseases. For Liver and vesicle, abdomen ultrasound is correct additional test but for pancreas is necessary to request a computed axial tomography(CAT scan). Your doctor, probably,will request because a person with weight loss and increased bilirubin levels, pancreas disease must be rule out. I wish you good health.(In case the answer would have been useful please indicate this)
