1. Gallery validation
4
First, read the GLU test. A yellow color show a good incubation
5
2. Add reagents
6
Four complementary tests must be realized.
TDA test : add 1 drop of FeCl³ reagent. IND test : add 1 drop of Kovacs reagent. 6
7
VP test : add 1 drop of a-naphtol reagent and
1 drop of KOH reagent. NR test : in the GLU test cup, add 1 drop of a-naphtylamin reagent and 1 drop of sulfanilic acid reagent.
