What Causes Elevated SGOT And SGPT Levels In Blood During Pregnancy?

Dear Doctor, With the last Blood test for my 22 week pregnant wife with our first baby, here are the results: Test Name          Result      Unit          Normal Range LFT Bilrubin - TOTAL 0.63 mg/dl          0.2 - 1.0 Bilirubin - DIRECT      0.14      mg/dl          0.0 - 0.30 SGOT                41.25      IU           5 - 38 SGPT                46.72      IU           5 - 40 Alkaline Phosphate 147.8      IU           80 - 306 Serum Protein      6.8       gms%          5.5 - 8 Albumin                3.8      gms%          3.5 - 5.5 Globulin           3.0      IU           2 - 4 A/G Ratio           1.27      Ratio          1 - 1.9 We are worried about the SGOT and SGPT levels being higher than normal. Is there anything to worry about? What implications could this have? Thanks
