Clinical Laboratory Chemistry Exam Questions with Correct Answers Latest Update 2025
Amperometry - Answers the measurement of the current flow produced by an oxidation-reduction
reaction
Wavelength - Answers the linear distance between any two equivalent points on a successive wave (nm)
Monochromator - Answers a device, for example diffraction grating or prism, used to isolate a certain
wavelength or range of wavelengths
Retention - Answers the time that has elapsed from the injection of a sample int the chromatograph to
the recording of the peak maximum of the component in the chromatogram
Isoelectric Point - Answers the pH at which the amino acid or protein has no net charge and the positive
charges equal the negative charges
Resolution - Answers Ability of a chromatographic system to separate multicomponent mixtures of
chemical compounds
Luminescence - Answers Emission of light or radiant energy when an electron returns from an excited or
higher energy level
Fluorescence - Answers The light (EMR) emitted by an atom or molecule after absorption of a photon.
The light energy is at a longer wavelength than the absorbed light and is usually emitted in less than 10-
8 seconds
Workstation - Answers Designated area in which limited numbers of specific tasks are completed
Carryover - Answers transport of quantity of analyze or reagent from one specimen to another and
contaminating subsequent specimen
Aliquot - Answers A known amount of a sample such as blood or urine
Discrete Testing - Answers term that applies to instruments that compartmentalized each sample
reaction
Throughput - Answers numbers of tests performed per hour
Test menu - Answers listing of all tests or analytes that an instrument is capable of measuring
Middleware - Answers example of software that allows a laboratory to connect their existing LIS and
instrumentation to facilitate automating information and performs tasks not currently done with
laboratories existing hardware and software
Microalbumin - Answers test used to diagnose or monitor diabetic nephropathy
Connecting Peptide - Answers peptide cleaved from proinsulin to form active insulin
