Career Escape
Moving from respiratory therapist to medical and clinical laboratory technicians, by the occupational data
Both occupations are described by the same O*NET 30.3 rating system, which makes them directly comparable: the same requirements, rated for each. What follows is that comparison for respiratory therapists and Medical and Clinical Laboratory Technicians, not an opinion about whether the move is a good idea.
Can a respiratory therapist become a medical and clinical laboratory technicians?
O*NET 30.3 rates 64% of what matters to either respiratory therapist work or medical and clinical laboratory technicians work as mattering to both, which is a real overlap with a real remainder. The requirements that carry across include Controlling Machines and Processes, Assisting and Caring for Others, Chemistry. Both sit at O*NET Job Zone 3, so the typical education, training and experience expected is the band you are already in. BLS does not publish a typical entry-education category for one of these occupations. What would be new concentrates in knowledge: Public Safety and Security, Administrative. O*NET describes the destination as follows: Perform routine medical laboratory tests for the diagnosis, treatment, and prevention of disease. This compares two occupations, not two people, and says nothing about whether any individual would be hired.
- Weighted overlap
- 64% of the requirements important to either occupation are important to both, with 3 of those shared requirements classed as distinctive rather than near-universal.
- Preparation level
- O*NET Job Zone 3, against Job Zone 3 for respiratory therapists. Not published.
- Typical entry education (BLS)
- Not published by BLS for this occupation.
- Prior experience typically expected
- Not published by BLS for this occupation.
- Where the overlap is strongest
- Knowledge, with 3 distinctive requirements important to both. Requirements that carry over include Controlling Machines and Processes, Assisting and Caring for Others, Chemistry.
- Independent corroboration
- O*NET does not list this as directly related to the source occupation; it appears one step out, related to a related occupation. The overlap measure and the relatedness file disagree here, and both are shown rather than one being quietly dropped.
Source and method
O*NET 30.3 Database, with BLS Employment Projections Table 5.4. Verified 2026-09-02. Importance ratings, Job Zones and occupational titles are read from O*NET. Typical entry education, prior experience and on-the-job training are read from BLS. The weighted overlap percentage, the distinctive-requirement counts, and the shared and new requirement lists are computed by RoleSprint from those inputs using the method published at /career-change/methodology.

RoleSprint-derived. Overlap percentages and the wage difference are calculated by RoleSprint from those published values. Limitation. These are national occupational statistics for two occupations. The wage figure is not a salary you would be offered, employment growth is not job security, and overlap is not a likelihood of being hired. Fields BLS does not publish for an occupation are omitted rather than estimated.
What carries over
Requirements O*NET rates as important for both respiratory therapists and medical and clinical laboratory technicianss, by domain. Most distinctive first, so the top of each list is the part that is actually worth putting on a resume.

Numbers are O*NET Importance, on a 1 to 5 scale. A requirement counts as important at 3.0 and above, which is the threshold the whole comparison uses.
What would be new
Requirements important for medical and clinical laboratory technicianss and not important for respiratory therapists. This is the part you would have to be able to evidence, and it is usually the real obstacle rather than the job title.

1 work activities rated important here and not for respiratory therapists.

Practical caveats for this move
Specific to this pair, and worth reading before treating any of the above as a plan.
- Medical and Clinical Laboratory Technicians sits at the same Job Zone as respiratory therapists, so the typical preparation band does not change. That removes one obstacle and none of the others.
- BLS records no prior experience in a related occupation as typical for this role, which makes the requirement lists above the more useful guide to what a posting will ask for.
- O*NET does not list this destination as directly related to your current occupation. It reached this map through the requirement overlap, one step out. That is a weaker corroboration than a directly related occupation, and it is shown rather than hidden.
- None of this accounts for licensing, geography, pay, hiring volume, or whether you would want the work. Occupational data describes the job. It does not describe the market for it, and it does not describe you.
How this move compares with the alternatives
This page is one move. The Opportunity Atlas puts every destination mapped from respiratory therapists side by side on skills overlap, day-to-day work, wage, projected growth, openings and the size of the training step.
It does not rank them, because the dimensions genuinely disagree: measured across every transition published here, how much your skills carry over and how much your knowledge carries over are close to unrelated. You choose which one matters and it orders by that.

Perform routine medical laboratory tests for the diagnosis, treatment, and prevention of disease. May work under the supervision of a medical technologist.

What to do next
Occupational data compares two jobs. It cannot tell you whether one specific employer would consider you, and this is the point where most people stop reading data and start applying blind.
