Basic laboratory bench skills: centrifugation, pipetting, aliquoting, and sample labeling. Comfortable working independently at a clinical site without direct on‑site supervision. Strong attention to detail and ability to follow SOPs precisely. Familiarity with universal precautions and safe handling of human biospecimens. Must carry active professional liability insurance. Must have an independently established business (LLC, sole proprietorship, or equivalent). Bilingual (English/Spanish). Nice to Have MLT (ASCP), MLS (ASCP), or California CLS credential.
