A recent liver function test puts sgpt/alt at 33, alkaline phosphate at 142, albumin at 3.1. are they indication of any problem?

May be: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your liver enzymes are not bad, but your albumin is low and suggests inadequate intake of protein. You should consider increasing your protein intake by eating meat. If you are a vegetarian, take more lentils, beans and tofu.
