BCG - Proteinuria & pH Applications

BCG albumin method quantifies serum albumin (2.5-4.5 g/dL) through selective dye binding at pH 4.2 preventing globulin interference.

Urine dipstick incorporates BCG detecting albuminuria >30mg/L confirming early diabetic nephropathy screening.

Yellow-green transition (pH 4.0-5.4) monitors acidification during tissue culture media preparation.

Succinate dehydrogenase histochemistry employs BCG trapping insoluble formazan products.
