Test Bank - Immunology and Serology in
Laboratory Medicine
Serology - ANSWERSStudy of the immunological properties of serum.
Serum - ANSWERSLiquid portion of blood without clotting factors (after clotting); collected in
tubes with no anticoagulant.
Plasma - ANSWERSLiquid portion with clotting factors; collected using anticoagulants.
Volumetric Pipettes - ANSWERSCalibrated for one specific volume (e.g., 5 mL). Used with
suction bulbs.
Graduated Pipettes - ANSWERSCan dispense variable volumes. Often blow-out pipettes (marked
with frosted band or 'TC' = To Contain).
Serological Pipettes - ANSWERSMarked to the tip; often used in dilution series.
Transfer Pipettes - ANSWERSBasic, uncalibrated; used when precision is not required.
Micropipettes - ANSWERSFor small, precise volumes (µL-mL range). Uses plunger and
disposable tips.
Specialty Pipettors - ANSWERSIncludes repeater pipette, multichannel pipette, and positive
displacement pipette.
Reading a Meniscus - ANSWERSAlways read the bottom of the curve (meniscus) at eye level for
accurate liquid measurement.
