OSHA…
Occupational safety and health administration
CLIA…
clinical Laboratory Improvement Amendments of 1988
Regulate labs testing human specimens and ensure they provide accurate, reliable, and timely patient test results no matter where the test is done.
HIPAA…
Health insurance Portability and Accountability Act - federal law that required the creation of national standards to protect sensitive patient health information from being disclosed without the patient’s consent or knowledge.
COLA…
Commission on Office Laboratory Accreditation - improving healthcare and patient care in labs nationwide through accreditation
NAACLS…
National accreditation agency for clinical laboratory sciences - the premier agency for international accreditation of educational programs in the clinical laboratory sciences and related health care disciplines
CMS..
Centers for Medicare and Medicaid Services - oversees all lab testing, except some research, done on humans in the U.S. through CLIA.
Normality =
grams of solute/ L solvent X equivalent weight
Molarity =
moles of solute/L of solvent
Dilution =
C1V1=C2V2
Sensitivity vs specificity
Sensitivity - the proportion of cases with a specific disease or condition that gives a positive result
Specificity - the proportion of cases with absence of the specific disease or condition that gives a negative test result
C =
(F-32) x 5/9
F =
(C x 9/5) + 32
a graph that quality control data is plotted on to give a visual indication whether the laboratory test is working well.
Levey Jennings chart
QC rules to help analyze whether or not an analytical run is in-control or out-of-control.
Westgard rules
Westgard rule:
One value > 3S. Out of control. Check and recalibrate equipment
1 3s
Westgard rule:
Two control values > 2S. Out of control. Check and recalibrate equipment.
2 2S
Westgard rule:
1 value out of 2S. Warning signs. Look for the next control level. If >2S then refer to previous rule.
1 2S
Westgard rule:
One control>2S and the other reading <2S. Out of control. Check and recalibrate equipment
R 4S
Westgard rule:
Four consecutive values > 1S. Systematic error.
4 1S
Westgard rule:
10 values on one side of the mean. Systematic error.
10X
Westgard rule:
7 consecutive values showing a similar trend. Indicates systematic error.
7T
Levey Jennings Chart:
S=
Shift - multiple consecutive control values on one side of the mean.
Levey Jennings Chart:
T=
Trend - Control value moves progressively in one direction for at least 3 days.
refers to how close a measurement is to the true or accepted value.
Accuracy
refers to how close measurements of the same item are to each other.
