regulation known by the employee
The blue filter modifies the yellow effect on the light giving it a more white light effect -
Answer-to eliminate the yellow color emitted by the tungsten light bulb
the oil immersion is used for? - Answer-it gathers light for the objective and increase
resolution. type B (high viscosity) is commonly used.
The X and Y in the microscope are used for: - Answer-the values obtained bared plotted
on the x and y axis. This moves the mechanical stage or base left to right and the y
moves up and down or front to back.
sharp container is an: - Answer-engineering control
NO sharps is in: - Answer-Biohazard bag
precision means: - Answer-closeness of repeat results (reproducibility). describes how
close test results are to one another when repeated analysis of the same material is
performed.
Accuracy - Answer-closeness of the results to the true value. describes how close a
given test result is to the true value

2SD - Answer-95.5%
3SD - Answer-99.7%
Systemic error - Answer-influences values consistency in 1 direction 2SD
REJECT RUN
Random error - Answer-exist in all measurements and due to chance 1 3SD
reject run
active error - Answer-interference between laboratorian and Patient's sample
Latent error - Answer-related to organization or design of a laboratory
variance - Answer-a term that describes the factor that affect the measurement of an
analyte
ex: sample error
random analytical error
analytical systemic error
operator error
sample- day to day sample variation within a single patient
patient- patient variation (race, sex, age, health status)
shift - Answer-refers to 6 consecutive points on one side of the mean
trend - Answer-refers to 6 consecutive points increasing or decreasing that may cross
the mean
NATIONAL FIRE PROTECTION agency hazard code: - Answer-RED= FLAMMABILITY
BLUE =HEALTH
YELLOW= REACTIVITY
WHITE= RADIOACTIVE ( MUST SEE OTHER HAZARD)
A mathematical measure of the spread (dispersion) of statistical data above and below
the average is called: - Answer-Standard Deviation
The etched rings on the top of the pipette mean: - Answer-that the last drop is to be
blown out after pipette drains
standard solution from 99.95 purity of the chemical can be retrieved are referred to as: -
Answer-primary standard
