If your red blood cells are being destroyed, this can result in a condition called hemolytic anemia. There are two types of Coombs tests: the direct Coombs test and the indirect Coombs test. The direct test is more common and checks for antibodies that are attached to the surface of your red blood cells.n abnormal result to an indirect Coombs test means you have antibodies circulating in your bloodstream that could cause your immune system to react to any red blood cells that are considered foreign to the body, particularly regarding those that may be present during a blood transfusion.
Generally, a typing speed of 40 WPM (Words Per Minute) is considered an average typing speed. A typing speed above 40 WPM (Words Per Minute) is higher than the average score, and over 100 WPM is usually considered a high speed (when it is achieved with zero errors).
In case if you donât know how average typing speed is measured, here are some brief descriptions of WPM, CPM and KPH: 1  Word Per Minute (WPM) is measured by calculating how many words (5 characters/keystrokes = 1 word) you can type in 1 minute. 2  Character Per Minute (CPM) calculates how many characters are typed per minute.
