Unless the SGOT levels are increased two or three times,it is not of that concern.
levels between 200-240 mg/dl are at borderline risk for heart disease
You didn't mention the values of other liver function tests like SGPT,Serum bilirubin
As Alchohol affects liver,it is better if you stop it completely.Avoid fatty foods also.
There is no hard and fast rule that your husband should have same values.
But,nothing to worry.
Everything will be alright once you meet your doctor.
Wish you good health.
