• Question 138:

  Because of the difficulty in culturing Epstein-Barr virus, and readily available heterophile antibody test and serology, it is rarely necessary to culture this virus in routine clinical practice.

  Micro

  Which one of the following viruses requires a complex lymphoblastoid cell culture, and is rarely if ever diagnosed by culture:

  A. Varicella-Zoster Virus

• Question 139:

  If all newborns were tested, many positive DATs due to ABO incompatibility would be detected that are of no clinical significance.

  Although many laboratories test infants born to group O Rh positive females due to the higher risk of ABO HDFN when the mother is group O, testing such infants is optional provided there is appropriate monitoring and follow-up for

  hyperbilirubinemia.

  Blood Bank

  Not performing direct antiglobulin tests (DATs) on newborns born to group O Rh positive mothers is acceptable good practice, providing there is appropriate surveillance and follow- up to detect hyperbilirubinemia.

  A. true

  B. false

  Correct Answer: A

• Question 140:

  A slow, progressive drift of values away from the mean is called a trend. Trends occur when a particular analyte value slowly and progressively changes in one direction from one run to the next. Monitoring data for trends is part of good laboratory practice and is one indicator of many that helps laboratorians determine whether the measurement system is fucntioning appropriately.

  A slow, progressive drift of values away from the mean is called a:

  A. Coefficient of Deviation

  B. Dispersion

  C. Trend

  D. Variance

  E. Sh

  Correct Answer: C
