Testing Laboratory Technician

Stefanini Group•Minneapolis, MN

About The Position

The Testing Laboratory Technician performs laboratory testing on fluid and process samples to detect and quantify cellular and particulate targets and distinguish true signals from common interferents, including red blood cells, fungal elements, and lipids. The role involves accurate sample handling, instrument operation, and thorough data logging so results can be grouped and trended by sampled material, fluid tube sizing, and sample aging. The technician receives, labels, and processes samples according to written procedures and chain-of-custody requirements; prepares and tests samples using approved methods and instrumentation; and documents target results, interferents, artifacts, observations, and deviations. The role also includes routine instrument setup and checks, basic troubleshooting, maintaining laboratory records and supplies, and supporting method improvements and investigations as assigned. Work is performed in a laboratory setting and may require personal protective equipment. The technician follows Good Documentation Practices and applicable quality system requirements, such as GLP. Work may involve standing, repetitive pipetting and bench work, and handling small containers and tubing components. The schedule may include time-sensitive testing based on sample collection windows and sample aging requirements.

Requirements

Associate degree or higher in laboratory science, biology, chemistry, medical laboratory technology, or equivalent experience.
Comfort working with biological fluids and following biosafety practices.
Strong attention to detail and demonstrated ability to document work clearly and follow written procedures.
Basic computer proficiency for data entry and file management.

Nice To Haves

At least 1 year of laboratory experience, such as sample handling, wet lab techniques, or analytical testing, is preferred; entry-level candidates with strong laboratory coursework are considered.
Experience with LIMS or ELN.

Responsibilities

Receive, label, and process fluid or process samples according to written procedures and chain-of-custody requirements.
Prepare samples and perform testing to detect or quantify cellular and particulate targets using approved methods and instrumentation.
Identify and document potential interferents and artifacts, including red blood cells, fungal elements, and lipids, and apply established criteria to distinguish them from target signals.
Perform routine instrument setup, calibration or verification checks, and basic troubleshooting; document out-of-spec conditions and escalate them according to procedure.
Maintain accurate, complete, contemporaneous laboratory records, including calculations, raw data, and observations.
Capture atypical findings, suggest refinements to decision criteria, and participate in investigations as assigned to support method improvements.
Maintain a clean and organized workspace, stock consumables, and maintain inventory levels needed for scheduled testing.
Log sample identifiers and collection metadata, including date and time, source, operator, volume, and deviations, to ensure traceability.
Record results and classification details, including counts or estimates, confidence flags, and notes, and separately document interferent observations using standard terminology.
Enter data in the approved format so results can be filtered, compared, and summarized across required groupings.
Record sample descriptors needed for grouping and trend analysis, including sampled material, fluid tube sizing and configuration when applicable, and sample aging details such as time from collection to test, storage conditions, and freeze/thaw or hold steps.
