Three-Minute Field Test Developed To Detect Syphilis  A new syphilis test has been developed that can be completed in three to eight minutes, and requires no test tubes, microscope or centrifuge. The test, called the Rapid Plasma Reagin Card test, was described Nov. 14 at the annual meeting of the Association of Military Surgeons in Washington.Joseph Portnoy, Ph.D., director of immunological research at Hynson, Westcott and Dunning, Inc., told the military physicians that the method was well-suited as a field test because of its simplicity. The Brewer plasma collection slide is used to obtain 'plasma for the serologic test. The slide is made of a plastic-coated board with a keyhole-shaped depression. The depression is coated with an anticoagulant and a lectin, stable at room temperature. This causes both red and white cells to clump, leaving the plasma free to flow into the collection slot.Three drops of blood
