<p>Diagnostic agent comprising:- (1) an absorbent support, or a film (2) a solid, strong acid (3) an Ehrlich reagent of formula (I) R1,2 = halogen, CN, NO, carbalkoxy, carbamido, OH, alkoxy, acyloxy, sec./tert.amino satd./unsatd. cyclic/open-chain; or R1+2 = O, S, SO2, alkylthionium, NH, alkyl-N, aryl-N opt. substd., dialkylimino heterocyclic alicyclic or open-chain; R2 may = aralkyl or alkyl mono/polycyclic or open-chain; R1 or R2 may=H, R3 = H, alkyl; n, m = 0-3. For the detection or determination of urobilinogens in body fluids, espec. in urine. More sensitive & less susceptible to error than known reagents. Detects 0.4 mg% urobilinogen in urine, unaffected by the presence of urea (even 3%), indican, indole or sulphonamides.</p> |
