- To determine whether there is a measurable protein background in different formulations of urinary and recombinant human chorionic gonadotropin (hCG). Primary outcome measures: identification of contaminant proteins in urinary‐derived formulations of hCG; secondary outcome measures: quantitative values of contaminant proteins in different batches of urinary –derived hCG formulations. It was found that urinary‐derived batches have high presence of contaminant proteins beside the active substance. The relative amount of contaminant proteins and hCG differs strongly between different batches.
