I purchased 500g of gallium for use in the series of museum displays I am helping build with Max Whitby of The Red Green and Blue Company: This 100g vial full was the tax I extract on all element samples that pass through my hands. I plan to use some of it to make a room-temperature liquid gallium-indium alloy.
The results of the rheumatoid factor (RF) test may be reported in titers or units: 1  A titer is a measure of how much the blood sample can be diluted before RF can no longer be detected.2  Nephelometry units show how much light is blocked by the blood sample in the tube.he results of the rheumatoid factor (RF) test may be reported in titers or units: 1  A titer is a measure of how much the blood sample can be diluted before RF can no longer be detected.
1 A rheumatoid factor more than 23 units and a titer more than 1:80 is indicative of rheumatoid arthritis but may also occur in other conditions. 2  False positive results can occur when the blood is high in fats.3  Inaccurate results can be caused by improper handling of the blood specimen.his test is most often used to diagnose rheumatoid arthritis. About 80% of patients with rheumatoid arthritis have positive RF tests. It may also be used to rule out or diagnose other inflammation-related conditions. Normal values depend on what method the laboratory uses to detect and measure the RF.
