A value ranging from 0 to 2 is assigned to the standard color: zero represents a negative; 5 represents a reaction of maximum intensity. Values 1 through 4 represent intermediate reactions depending on the level of intensity. The approximate activity may be estimated from the color strength: 1 corresponds to the liberation of 5 nanomoles; 2, to 10 nanomoles; 3, to 20 nanomoles; 4, to 30 nanomoles; and 5, to 40 nanomoles or more.
