MLSP: Clinical Chemistry Flashcards
Most automated area of the laboratory
CLINICAL CHEMISTRY SECTION
T or F
In Clinical Chemistry Section, instruments are computerized and designed to perform single and multiple tests from small amounts of specimen
True
T or F
Areas in clinical chemistry; general, electrophoresis, toxicology, immunochemistry.
True
routine chemistry tests: glucose, protein, etc
General or automated chemistry
specialized procedure (not really an area) for chemistry analysis; specimen is placed
on a gel-like medium and when the electric current
hits that, there will be a separation on different
components in that specimen
Electrophoresis
area that monitors drugs of abuse
Toxicology
immune assays and
immunologic reactions
Immunochemistry
T or F
Tests are performed primarily on serum collected in gel barrier tubes, but the serum may also be collected in tubes with red, green, gray, or royal blue stoppers.
True
appear red because of
the release of hemoglobin from rbcs [rejected]
Hemolyzed specimens
appear yellow because of
the presence of excess bilirubin [significant; microscopic]
Icteric specimens
are cloudy [gelatin-
like] because of increased lipids artificially made when the patient ate fatty meal before blood collection; if not, it is an indicator of something else
Lipemic specimens
The response time for the collection of this test
sample is determined by each hospital or clinic and
may vary by laboratory tests.
ASAP SAMPLES
the sample is to be collected, analyzed, and results reported immediately.
STAT SAMPLES
highest priority and are usually ordered from the emergency department or for a critically ill patient
STAT SAMPLES
The patient must only have refrained from eating and drinking (except water) for 12 hours
FASTING SAMPLES
Hormones [specific time; follow instructions]
TIMED SAMPLES
For the diagnosis of diabetes mellitus and gestational diabetes increase in blood sugar during
pregnancy
GLUCOSE TOLERANCE TESTS
Recommended method for the diagnosis of diabetes mellitus.
2-HOUR ORAL GLUCOSE TOLERANCE TEST
Diabetes mellitus= ≥200 mg/dl
- Kukuhanan dugo
- Papainumin ng glucose sample
- Kukuhanan ulit ng dugo
2-HOUR ORAL GLUCOSE TOLERANCE TEST
Utilizes the same procedure as the diagnostic OGTT used to diagnose diabetes mellitus [glucose drink given only once]
Normal value: ≤ 140 mg/dl
ONE-STEP METHOD FOR GESTATIONAL DIABETES
Requires the patient to receive two tests.
Normal Values:
2-hour 75-g test: 155mg/dL
3-hour 100-g test: 140 mg’dL
TWO-STEP METHOD FOR GESTATIONAL DIABETES
Evaluates a patient’s ability to digest lactose, a milk sugar.
LACTOSE TOLERANCE TEST
A blood collection schedule is similar to a 2-hour GTT.
LACTOSE TOLERANCE TEST
