Causes for a high SGOT level can include infection, viral hepatitis, mononucleosis, gallbladder disease, the presence of toxins from drugs or alcohol and cancer. It may also indicate muscle damage from a fall or injury, or a muscle disease such as polymyositis or muscular dystrophy.
Basements or crawl spaces. Basements are often overridden with moisture. There is often a substantial amount of moisture coming through the concrete. Some houses can have up to 100 pints of humidity that needs to be removed per day, most of it coming through the basement in some cases. For a basement, it is recommended to keep moisture at least under 65% although the optimal room humidity would be between 40%-50%.
What you want to avoid is prolonged exposure to low humidity. A relative humidity level between 40% and 50% is generally considered to be the most comfortable. Anywhere from 30% to 60% is acceptable, but ideally you want to avoid the extremes of that range.
