Hi, my wife is 26 week pregnant and now her sgpt level is 280. baby weight is 900gm. could you please advice what should we do now?

It depends: It depends on the reason for the elevation. If it is HELLP syndrome or acute fatty liver, delivery is necessary for both mom and baby and should be in a high risk setting. If it is gallstones she needs her gallbladder out. There are several other possibilities. She should be cared for by a maternal-fetal medicine specialist and should follow the recommendations for her specifically.
