My albumin, globulin values came slightly off in blood test. Albumin: 5.1 gm/dl (normal 3.5-4.8) globulin: 2.1 gm/dl (normal 2.5-3.2) shd I worry?

How do you feel? First thing to consider is dehydration. Next time you take the test, make sure you are well hydrated, even though you were asked to come fasting; that does not exclude drinking water. If you do not have symptoms, there is no need to worry.
