1.) Blood samples are commonly used in diagnostics for identifying genetic diseases when the disease is caused by a mutation(s) in a specific gene. If you were in the Clinical lab and needed to run a test for this disease on a sample of blood from a hematocrit sample, what fraction(s) of the hematocrit would you use for performing this test and explain why?

2.)If the EDTA that coated the vacutainer when collecting the cows blood was too high relative to the amount of cow blood collected, this can result in the shrinkage of RBCs. Indicate which of the measurements you mad ein this lab for counting blood might be affected by this error? Would this error result in an over estimation of the measurement or an under estimation of the measurement?

Solution

Genetic test can be done from blood sample .Only few micro liter of blood is required in these test DNA is analyzed for mutation. That linked with genetic disease.

2.EDTA ethylene diamond tetraacetic acid is an anticoagulant if the concentration will increased it can affect leukocyte count, neutrophill percentage also get affected. Erroneous result can come .
