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).
For example, a score of 53 words per minute with 15 errors would be lower on the list than a score of 53 words per minute with 2 errors. THE RESULTS Figure 1 shows the distribution of all typing speed scores. Since our Mean was 40 and our Median 38, our statistically average typist is between 38 and 40 WPM. Someone who typed 56 is in the top 20% of all typists in the sample. A score of 65 is in the top 10% of the sample.
