How does ERP compare to GL Biochem (Shanghai) on documentation quality?

Asked 10 Jul 2024Modified 2.1 years agoViewed 38k times

Stated plainly: ERP · GL Biochem (Shanghai).

Both of these get recommended confidently by different people, which suggests neither is obviously right.

My constraints are cost, measurement resolution and how much handling I am prepared to do — in roughly that order.

Is there a defensible reason to prefer one, or is this a coin flip?

Good answer, but the confidence interval in the cited trial is wider than implied. – kirsi_lahtinen 3 months ago
