The blood type of sample A is… (B) When unknown sample B was tested, no agglutination (clumping) of red blood cells occurred in any tests. The blood type of sample B is… (C) When unknown sample C was tested, agglutination (clumping) of red blood cells occurred in test 2 and 3, but not 1. The blood type of sample C is…

GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved immunoglobin A (70. to 312. mg/dL), using a blood sample that is as small as 250 µL. Calculate the minimum mass in milligrams of immunoglobin A that the new system must be able to detect. Be sure your answer has the correct number of significant digits. mg 0 x10 X
