Core Technical Laboratory Skills

Technical skills form the foundation of your work as an MLT. These skills involve performing laboratory tests, operating sophisticated laboratory equipment, and following standard operating procedures across disciplines like hematology, chemistry, microbiology, immunology, and urinalysis. In practical terms, this means you’ll process biological samples, perform complex tests, and generate the test results that doctors use to guide patient treatment.

Specimen Processing Competency

Before any test can be performed, samples must be handled correctly. Your responsibilities include:

• Verifying proper labeling with two patient identifiers (full name and date of birth or medical record number)
• Performing centrifugation at correct speeds and times
• Aliquoting samples into appropriate containers
• Storing specimens at required temperatures (for example, refrigeration at 2–8°C for certain chemistry samples)
• Documenting sample preparation steps and any issues encountered

Instrument Operation

Modern laboratories rely heavily on automated analyzers. You’ll need to master equipment from manufacturers like Sysmex (hematology), Roche, and Abbott (chemistry). Daily tasks include:

Task	What It Involves
Loading specimens	Placing properly labeled tubes in the correct racks and positions
Selecting test menus	Choosing appropriate assays based on the physician's orders
Running controls	Processing quality control materials at the start of each shift
Recognizing flags	Identifying instrument alerts that indicate potential problems

Quality Control and Calibration

Performing quality control is non-negotiable. You’ll need to interpret Levey-Jennings charts to spot trends, know when to stop testing if controls fall out of range, and understand calibration principles that ensure accurate recording of patient values.

Technology and Laboratory Information Systems Skills

Modern medical laboratory technicians work with both physical instruments and digital systems daily. Your comfort with medical technology must extend beyond the bench to the software that manages every aspect of laboratory procedures.

Basic Computer Literacy

You’ll work on Windows-based workstations throughout your shift. Essential skills include:

• Typing efficiently for data entry and documentation
• Navigating shared network drives to access standard operating procedures (SOPs) and reference materials
• Using basic troubleshooting steps when systems freeze or perform unexpectedly

Laboratory Information Systems (LIS)

The LIS is your primary digital workspace. Platforms like Epic Beaker, Sunquest, and Cerner Millennium PathNet handle order entry, specimen tracking, result verification, and reporting. You’ll log quality control (QC) results, use middleware for autoverification of routine results, and investigate delta checks flagged when current results differ significantly from previous values.

Electronic Medical Records Integration

While your primary focus is the LIS, you’ll also access electronic medical record (EMR) systems like Epic or Cerner PowerChart to view patient history or correlate current laboratory results with previous findings. This data analysis capability helps you spot inconsistencies that might indicate a problem with the sample rather than a true clinical change.

Troubleshooting Technology Issues

Interface problems between analyzers and the LIS happen regularly. You’ll need to recognize when barcode scanning fails, resolve common connectivity issues, and know when to escalate persistent problems to IT or vendor support. These technical training skills keep the laboratory running smoothly.

Attention to Detail and Accuracy

In a medical laboratory, attention to detail isn’t just a nice-to-have; it’s a patient safety imperative. A single-digit error, a misplaced decimal, or a unit confusion (mg/dL versus mmol/L) can mislead clinicians and potentially cause patient harm. Your ability to maintain accuracy across various tasks directly affects the quality of care patients receive.

The “Right Patient, Right Test, Right Time” Principle

Every specimen you handle requires verification. Before processing, confirm:

• Patient’s full name matches the order
• Date of birth or medical record number is correct
• Specimen type and collection time are appropriate for the ordered tests
• No discrepancies exist between labels and requisition information

Following SOPs Step by Step

Laboratory procedures exist for a reason. Whether you’re performing a rapid strep test with a specific incubation time or running a coagulation assay that requires precise timing, following each step exactly as written ensures reproducible, reliable results. This includes documenting lot numbers, checking reagent expiration dates, and adhering to proper handling requirements.

Data Verification

When reviewing results before release, watch for:

• Instrument flags indicating potential interference
• Critical values requiring immediate notification
• Results that seem physiologically implausible
• Patterns suggesting pre-analytical problems

Analytical and Problem-Solving Abilities

Analytical skills for MLTs go beyond performing tests. They involve interpreting results, recognizing patterns, and knowing when something doesn’t make clinical or technical sense. These problem-solving abilities separate competent technicians from exceptional ones.

Basic Data Interpretation

As a medical laboratory technician, you’ll develop the ability to correlate laboratory results. For example:

• Comparing white blood cell (WBC) count with the differential to assess infection patterns
• Relating glucose levels to HbA1c for diabetes monitoring
• Recognizing when electrolyte values don’t fit expected clinical pictures

Troubleshooting QC Failures

When controls fall out of range, you’ll follow a systematic approach:

1. Check reagent expiration dates and storage conditions
2. Review instrument maintenance logs for recent issues
3. Verify calibrator lot numbers and preparation
4. Rerun controls before releasing patient samples
5. Document all corrective actions taken

Problem-Solving Under Pressure

Emergency situations test your analytical skills intensely. During a trauma case with STAT orders, your analyzer may display repeated error codes. You must quickly determine whether the problem is reagent-related, mechanical, or sample-specific, all while the emergency department team awaits critical results.

Knowing When to Escalate

Not every problem has an immediate solution at the technician level. Recognizing when to consult a senior technician, lead MLT, pathologist, or medical laboratory scientist for complex procedures or unusual findings demonstrates good professional judgment.

Communication and Teamwork Skills

Although laboratory technicians often work behind the scenes, effective communication with nurses, physicians, phlebotomists, and fellow laboratory staff is essential. These soft skills ensure critical information reaches the right people at the right time.

Verbal Communication

When calling critical values, such as positive blood cultures, dangerously high potassium, or severely low hemoglobin, you must:

• Clearly state your name, department, and the patient identifier
• Report the critical result precisely
• Use read-back procedures where the receiving party repeats the information
• Document who received the result, when, and any instructions given

Written Communication

Your documentation in the LIS must be accurate and concise. You’ll add comments explaining specimen issues (hemolyzed, lipemic, insufficient volume), note any deviations from standard procedures, and complete incident reports when problems occur.

Teamwork Across Shifts

Laboratories operate 24/7, requiring smooth hand-offs between day, evening, and night shifts. Effective team members:

• Communicate outstanding issues during shift change
• Support colleagues during high-volume periods like flu season
• Cross-cover other benches when coworkers handle urgent situations

Organization, Time Management, and Consistency

Laboratories process hundreds or thousands of specimens daily. Your ability to organize workflow, prioritize tasks, and maintain consistent performance directly impacts turnaround times and result reliability.

Organizing Workflow

Effective organization strategies include:

Strategy	Application
Batching similar tests	Running all chemistry panels together for efficiency
Using rack systems	Color-coding or labeling of STAT versus routine samples
Planning ahead	Using slower periods for preventive maintenance or reagent inventory
Maintaining clean workspaces	Keeping reagent areas labeled and uncluttered

Time Management

Balancing multiple priorities requires constant awareness. You’ll monitor turnaround times for critical assays, manage multiple timers simultaneously, and ensure STAT orders receive appropriate prioritization without neglecting routine work.

Consistency in Procedures

Regulatory compliance depends on performing complex procedures the correct way every time. Whether it’s how you label tubes, the order you load specimens, or how you document QC, consistency ensures reproducible results and supports accreditation requirements from bodies like the College of American Pathologists (CAP) or The Joint Commission.

Professionalism, Ethics, and Safety Mindset

Every day, you’ll handle confidential patient information, body fluids, chemical samples, and potentially hazardous materials. A strong ethical foundation and safety mindset protect both patients and yourself.

Confidentiality and HIPAA Compliance

Patient privacy is paramount. Essential skills include:
