Question 1

During the hour that an ESR is allowed to sit while the red blood cells settle, the tube must remain undisturbed.Short Answer

C)Reading the result for the ESR at 50 minutes
D)All of the above
Multiple Response
Identify one or more choices that best complete the statement or answer the question.
