Okay, let’s tackle this. So Andrew Luo has 16 years of experience as a laboratory technologist, which is a significant amount of time. His expertise in karyotyping is also a highly specialized skill. Location is Hong Kong, which is a hub for biotechnology and life sciences. Laboratorians with his level of experience, especially in a specialized field like karyotyping, typically charge lower rates. Maybe around $50–$100 per hour? But considering his experience and expertise, maybe higher. Some laboratory professionals with similar experience might average $75–$125. So I’ll estimate around $75.
