The expert reading was performed blinded from the other readings.
A second reading was performed 48 h after removal of the patch (Table 2) Both readings are essential because of difference in kinetics of allergic and irritant contact reactions in vivo [ 4, 19].
In the case of disagreement, a joint reading was performed and a consensus decision was reached.
The material was stratified into two groups depending on whether the double reading was performed by a colleague of similar or higher sub-specialty.
First the top surface was made and the sample was putted back to the water recipe while the reading was performed at another sample.
A staged reading was performed at The Public Theater in 2011.
Plate reading was performed after each cycle.
Subtraction of the field potential from the ion-sensitive electrode voltage reading was performed.
In "standard mode" reading was performed by direct observation through the eyepiece by the laboratory technician.
The reaction was stopped with 25 µL hydrochloric acid 103 M and reading was performed at 450 nm.
If results disagreed (positive vs negative, or marked difference in density), a third independent reading was performed, and the two closest results were averaged.
