What does ANA titer 1 160 mean?
Titers ≥ 1:160 usually indicate the presence of active SLE, although occasionally other autoimmune disease may induce these high titers. There are now known groups of ANA-negative lupus patients.
What does an ANA titer of 1 40 mean?
An ANA titer of 1:40 or higher is considered positive. An ANA titer of less than 1:40 is useful for ruling out SLE in children (sensitivity of 98%). A repeated negative result makes a diagnosis of SLE unlikely but not impossible. The ANA titer does not correlate with the severity of the disease.
What does ANA titer 1 80 speckled mean?
The higher the titer, the more likely the result is a “true positive” result, meaning you have significant ANAs and an autoimmune disease. For example, for a ratio of 1:40 or 1:80, the possibility of an autoimmune disorder is considered low.
Is an ANA of 160 high?
A titer of 1:160 or above is commonly considered a positive test result. Other conditions with ANA associations include Crohn’s disease, mononucleosis, subacute bacterial endocarditis, tuberculosis, and lymphoproliferative diseases.
What is highest ANA titer?
In our laboratory, an ANA titer of 1:640 is defined as a “high titer” because of a 0.5% prevalence of positives in normal individuals. Therefore, we divided the patients into a high titer group (≥1:640) and low titer group (<1:640).
Who are the prime contractors for the Naval Nuclear Propulsion program?
Since the late 1950s, the Naval Nuclear Propulsion Program has had dedicated prime contractor support to provide engineering, procurement, and technical oversight of naval nuclear components. Currently, the prime contractor is Bechtel Plant Machinery, Inc. (BPMI), with locations in Pittsburgh, Pennsylvania, and Schenectady, New York.
What do you need to know about the Navy reactors?
About Naval Reactors. The Naval Nuclear Propulsion Program provides militarily effective nuclear propulsion plants and ensures their safe, reliable and long-lived operation. This mission requires the combination of fully trained U.S. Navy men and women with ships that excel in endurance, stealth, speed, and independence from supply chains.
How many nuclear-powered ships does the United States have?
Currently, the U.S. has 83 nuclear-powered ships: 72 submarines, 10 aircraft carriers and one research vessel. These NPWs make up about forty percent of major U.S. naval combatants, and they visit over 150 ports in over 50 countries, including approximately 70 ports in the U.S. and three in Japan.
