Medical Laboratory Scientist, Core Lab and Blood Bank, Trey Research Medical Center
Dear Howard Lin,
I'm applying for the Medical Laboratory Scientist position in Trey Research Medical Center's core lab and blood bank. I'm certified as MLS(ASCP)CM, with 6 years in hospital and outpatient labs. At Minnehaha Falls Medical Center I run and verify chemistry, hematology, coagulation and urinalysis results for a 300-bed hospital on evening shift.
Your posting asks for blood bank experience. I perform ABO/Rh typing, antibody screens and crossmatching and issue products during massive transfusion events. I also review daily QC with Westgard rules, troubleshoot analyzer failures and document corrective action before any patient result goes out, and I call critical values with read-back and log each call in the LIS.
I've also helped bring new instruments into service. I ran precision, accuracy and reportable range studies to validate our new coagulation analyzer for the lab director's sign-off. Earlier, at Lake Nokomis Clinic Laboratory, I cut average turnaround time for routine morning chemistry from 3 hours to under 2 by reorganizing batch runs, and I trained 5 MLS students on hematology.
I'd welcome the chance to talk about how your lab covers its evening and weekend shifts. Thank you for considering my application.
Sincerely,
Kevin Tran

Something else? support@launch-cv.com
Do medical laboratory scientists need a cover letter?
Not always. Many hospital labs hire from the application. A short letter helps when you're moving into a new department, such as blood bank, or into a lead role.
What should a new graduate MLS write about?
Your NAACLS-accredited program, ASCP exam status and clinical rotations, with the departments and instruments you trained on.
