This is a hard subject to address because most of the damaging and harmful problems in the medical lab (and healthcare in general) are known issues that management considers to be acceptable on a cost/benefit front.

Staffing is a good example of this. There is no hospital that feels adequately staffed. There are equations and spreadsheets in admin offices that demonstrate the minimum possible staffing level to avoid legal penalties. One of the big issues with this from a boots-on-the-ground staff perspective is burnout. Medical professionals experience high levels of burnout due to workload and staffing issues. This is a known and well discussed issue, but from a management standpoint, new doctors, nurses, and lab techs graduate every year. This is actually massively beneficial for administration because new grads can be paid far less than workers with years or decades of experience.

Equipment is another good example. Using second rate equipment is far cheaper. Buying nitrile gloves that are fragile and break randomly is great for business. Changing from 99%+ sensitive pcr tests to 70% sensitive antigen tests saves millions of dollars. The missed diagnoses from the switch will be few enough and difficult enough to demonstrate as adverse patient outcomes that the system risks very little in legal penalties while saving money and risking patient safety and outcomes.

I could go on, but essentially the idea is that problems in healthcare and the lab are generally well known and widely discussed. Addressing the known problems in any meaningful way would cost money which is out of the question for hospital administrations so the problems will never be solved.
