Big pharma has its own QC labs. But small biotechs and virtual companies outsource to CROs. The pharmaceutical quality control market research study shows that CROs are the fastest‑growing end‑user segment, with a CAGR above 9%. Why? Because building and validating a QC lab costs $5‑10 million — too much for a startup. CROs offer flexible, pay‑as‑you‑go services.

What do CROs test? Raw materials, in‑process samples, final product, and stability batches. The pharmaceutical quality control market trends highlight that the fastest‑growing testing type is extractable and leachable — analyzing what leaches out of plastic bags, tubing, and stoppers into the drug product.

But CROs have a downside: loss of control. You're trusting someone else with your data. And if they make a mistake, your timeline slips.

The message: if you use a CRO, audit them regularly. And always have a backup plan.
