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.
When an initial PTT is prolonged, a second PTT test is performed by mixing the person's plasma with pooled normal plasma (a collection of plasma from a number of normal donors). If the PTT time returns to normal (corrects), it suggests a deficiency of one or more of the coagulation factors in the person's plasma. If the time remains prolonged, then the problem may be due to the presence of an abnormal specific factor inhibitor (autoantibody) or nonspecific lupus anticoagulant.
