1A positive result is >10 IU/mL, equivocal 5.0 to 9.9 IU/mL, and negative 0.0 to 4.9 IU/mL. Results were available in 181 (69%) of 261 students.
2A positive result is >0.70 relative fluorescence value (RFV), equivocal >0.50 to <0.70 RFV, and negative <0.50 RFV. Results were available in 180 (69%) of 261 students.
3A positive result is >0.50 RFV, equivocal >0.35 to <0.50 RFV, and negative <0.35 RFV. Mumps serology was available in 170 (65%) of 261 students.
4A reactive test is >1.0 relative light unit (RLU) and nonreactive <1.0 RLU. Results were available in 168 (64%) of 261 students.
5A reactive test is >10.0 mIU/mL and nonreactive <10.0 mIU/mL. Results were available for 181(69%) of 261 students.
6A positive result is >0.90 RFV, equivocal 0.60 to <0.90 RFV, and negative <0.60 RFV. The titer was available in 182 (70%) of 261 students.
7Please refer to the manufactures’ brochures. Results were available only in 182 (70%) of 261 students. Equivocal test indicates indeterminate.
