How to Showcase Skills on Your Resume

Healthcare ATS platforms scan for specific terminology. Generic descriptions like "lab work" or "testing" will not trigger keyword matches [1].

Name Your Instruments. Instead of "operated chemistry analyzer," write "Operated Roche Cobas c702 chemistry analyzer processing 800+ specimens per shift." Recruiters and ATS systems search for specific analyzer names.

Specify Testing Departments. Organize your experience by laboratory section: hematology, chemistry, microbiology, blood bank, urinalysis. This mirrors how job postings are structured and ensures keyword coverage.

Include Certifications Prominently. ASCP certification is a primary filter in many healthcare ATS systems. Place it near the top of your resume alongside your name and credentials.

Quantify Workload. "Processed an average of 200 specimens per shift with a 99.7% accuracy rate" is stronger than "responsible for specimen processing."

Use Standardized Terminology. Write "CBC with differential" not "blood count." Write "antimicrobial susceptibility testing" not "sensitivity testing." Precision in language signals competence and matches ATS keywords.

Highlight QC and Compliance. Mention specific accreditation bodies (CAP, AABB, COLA) and regulatory frameworks (CLIA, OSHA). Compliance awareness is a hiring priority.
