Basic Clinical Chemistry/Serology
Practicum Performance Objectives
- The student should perform the following clerical
and sample preparation procedures:
- Identify name, time, and date and correlate these
with specimen request.
- Process samples in an appropriate manner
(centrifugation, refrigeration, etc.).
- Organize workload in separating, labeling, and
dispensing sample.
- Construct daily work sheets for workstation.
- Prepare work reagents and solutions.
- Prepare and organize samples, QC reagents, and
supplies for a test run.
- Determine suitability of sample for analysis.
- Use appropriate safety precautions in handling
specimens.
- At any workstation, the student should be able to
handle sample analysis as follows:
- Perform an acceptable test run with minimal
assistance.
- Determine acceptability of test run results.
- Perform dilutions on urine or serum patient samples
as necessary
- Make any appropriate calculations necessary to
report results.
- Record or enter test results using proper computer
technique.
- Recognize and properly handle abnormal test results
with regard to notifying the supervisor, pathologist, and/or physician.
- Recognize and discuss possible disease states
related to values obtained.
- For blood gases; be able to distinguish between
metabolic and respiratory acidosis and alkalosis.
- Students should perform routine chemistry analyses
during their clinical chemistry rotation using at least one discrete
analyzer and one batch or profiling analyzer:
- Routine chemistry blood panels
- Osmolality (serum, urine)
- Lipid panels: cholesterol, HDL cholesterol,
triglycerides
- Urine routine chemistries (protein, creatinine,
amylase, glucose, Na, K, etc.)
- CSF routine chemistries (protein, glucose)
- Arterial blood gases (pH, PCO2,
P02, calculated values)
- At least 2 manual special chemistries (glycated
hemoglobins, porphyrin screen, myoglobin, gastrics, plasma hemoglobin,
serotonin, lithium, sweat chloride, cryoglobulin, porphobilinogen, etc.)
- Toxicology: ethanol, salicylates, carbon monoxide,
etc. if routinely done in your laboratory
- Serological assays: see list at the end of
objectives
- For any automated or semi-automated analyzers used
in teaching including blood gas analyzers and back up instrumentation, the
student should be able to:
- Perform start-up and shutdown procedures and daily
maintenance
- Properly calibrate the instrument if needed
- Perform and record correct quality control measures
- Conduct specimen assays
- Demonstrate adequate knowledge of principles of
operation
- Troubleshoot with supervision at least one
instrument malfunction problem that requires using the instrument manual's
troubleshooting guide and/or a phone call to the technical service
department.
- For Quality Control, the student should do the
following:
- Follow protocol for recording QC results and take
the proper steps if results are out of control.
- Prepare reagents and perform and record appropriate
lot # quality control checks on the reagents for at least two different
procedures or instruments (may include evaluating new lot numbers of
reagents).
- Perform preventative maintenance on at least one
piece of automated equipment other than daily start-up or shutdown
procedures.
- Student must demonstrate computer literacy by
successfully performing the following:
- Enter patient results and release, if applicable
- Inquire for patient results on demand.
- Perform delta checks on patient results under tech
supervision.
