Siding Options. The popular choice out there is vinyl because theyâre cost effective and easy to install and maintain. Some things to consider with vinyl is that the color can fade, and the siding become brittle with time. For homeowners who prefer to go with wood, there is hardwood, cypress, clapboard, wood shingles, and plywood siding.
Digestive System. Elevated PTT results may be caused by malabsorption, a digestive problem that restricts the amount of nutrients that the body absorbs from food, according to the U.S. National Library of Medicine.
Another cause of elevated liver transaminase levels is muscle injury. Strenuous exercise or myopathy can cause elevations (especially of AST) without causing any other symptoms. A creatine kinase or other muscle marker can be obtained to confirm or exclude such a process.
