WHEREIN X is a stabilizing anion; R1 and R2, which may be the same or different, are halogen or lower alkyl or alkoxy and R3 and R4, which may be the same or different, are hydrogen, halogen, nitro, or lower alkyl or alkoxy; THE AROMATIC RING IN FORMULA (I) containing either (a) 1 to 3 halogen atoms or (b) one nitro group, but not both together; and an amount of an acid sufficient for a coupling reaction between bilirubin and said diazonium salt.
Bilirubin, particularly as contained in body fluids, is determined with test strips comprising an absorbent

Diagnostic agents for use in the detection of urobilinogen materials in body fluids such as urine, the agents comprising at least one strong acid and at least one compound which reacts with urobilinogen materials present in the body fluids to provide analytically measurable dyestuffs wherein said compound has the formula:
IN WHICH R1 and R2 which may be the same or different, each represent halogen, cyano, nitroso, carbalkoxy, carbamido, hydroxy, acyloxy, alkoxy, straight-chained and cyclic, saturated and unsaturated secondary and tertiary amino, or R1 and R2 together represent oxygen, sulfur, sulfonyl, alkylthionium, imino, alkylimino, substituted or unsubstituted arylimino or open-chained, alicyclic or heterocyclic dialkylimino, R2 can also represent the residue of secondary straight or branched, openchained or mono- or polycyclic alkyl or aralkyl and wherein one of R1 and R2 can also represent hydrogen, R3 is hydrogen or alkyl, and n and m which may be the same or different each have a value of 0, 1, 2 or 3.
摘要:
Mucoviscidosis (cystic fibrosis) is detected in its early stages, particularly in the large-scale screening in newborn infants, by means of measuring the pathologically elevated protein content in the meconium, using a diagnostic agent comprising a protein test strip sealed to a longer plastic strip, applying meconium to the (flush) bottom portion of the combined strip, immersing the smeared portion of the strip in water, permitting water to wet the strip by ascending chromatography, and reading a color change in the strip as an indication of elevated protein content in the meconium.
