A positive tTG with a negative gliadin can mean a number of things: You got a false positive tTG. (Possibly due to some other autoimmune disorder) You got a false negative gliadin. (This is actually much more likely than with the tTG test. Reported sensitivity of gliadin test is in the 65-75% range, meaning that roughly 1/4-1/3 will be false negative)
Definition of ultra. : going beyond others or beyond due limit : extreme.
From Wikipedia, the free encyclopedia. Ultrabook was created as a specification and trademarked brand by Intel for a class of high-end subnotebooks designed to feature reduced bulk without compromising battery life. They used low-power Intel Core processors, solid-state drives, and unibody chassis to help meet these criteria. Due to their limited size, Ultrabooks typically omitted common laptop features such as optical disc drives and Ethernet ports. Ultrabook is a portmanteau of words ultraportable and notebook.
