A substance that is being identified or measured in a laboratory test.
A mechanism of a test system to determine if the system is providing accurate results.
To ensure that test results are reliable and valid, and errors that may interfere with obtaining ac-curate test results are detected and eliminated.
RBC of 3 cell/mm3 * An RBC of 3 cell/mm3 is low for newborns, children, and adult males and females. A low RBC count is a sign of anemia. Hemoglobin level of 9 g/dL *A hemoglobin level of 9 g/dL is low for both adult males and females. A low hemoglobin level is a sign of anemia.
It is a low value for an adult male. The normal value for an adult male is 14-18 g/dL. so 12 g/dL is low.
1. Mean corpuscular volume of 120 cell/mm3 The normal mean corpuscular volume (cells/mm3) is between 80-95. A mean corpuscular volume of 120 cell/mm3 is high. A high mean corpuscular volume indicates chronic liver disease. 2. Mean corpuscular hemoglobin of 39 pg/cell The normal range for mean corpuscular hemoglobin (pg/cell) is 27-31. A mean corpuscular hemoglobin of 39 pg/cell is high. A high mean corpuscle hemoglobin indicates chronic liver disease.
Made of: 1. intracellular: inside cell (2/3) 2. extracellular fluid (1/3) >interstitial fluid(3/4) >intravascular fluid: fluid inside blood vessel(1/4)
- intracellular fluid - interstitial fluid *extravascular: between blood and intestinal there is rapid exchange of fluid
substance or constituent for which a laboratory conducts testing
a range established for test results assumed to be typical for a population asymptomatic for disease processes
a large facility in which thousands of tests various types are performed each day
often necessary to evaluate disease progression and response to therapy or to monitor development of toxicities associated with therapy
Repeatability of a lab test (i.e., test results fall within a similar value when repeated)
Ability of a test to provide a result that is reflective of the "true" value (i.e., test result matches actual real value)
hyper......- or -....cytosis
hypo...- or -....penia
Seven tests that analyze metabolism -Electrolytes -Kidney function -Glucose -Acid/Base Balance Also known as a "Chem 7"
Cocci are spherical bacteria. Bacilli are rods. Spirochetes are spiral shaped. A nematode is a parasite, not a bacterium. Pleomorphic describes variably shaped organisms.
Interestingly, red blood cells are normally nucleated in birds and reptiles. Nucleated red blood cells can be seen in other species whenever there is a demand on the body to rapidly release red blood cells into the bloodstream. If demand exceeds the bone marrow's production capabilities, the body will begin to release juvenile red blood cells, which still have a nucleus.
"Seg" is short for segmented neutrophil.

the science of using the chemical analysis of bodily fluids to obtain information about the clinical condition of the body.
By an abbreviation that is the first 1 or 2 letters of the clinical name.
electrically charged chemicals.
Function: Total leukocyte count. Subdivided into 5 types in differential Determines the presence of infection Nursing Implications Check VS, note if temp and pulse increased Assess for s/sx of infection
Function: Carries oxygen Nursing Implications: Assess for causes and s/sx
Function: Iron component of RBC that carries oxygen Nursing Implications: Assess for causes and s/sx s/sx of anemia: dizziness, tachycardia, weakness, fatigue, dyspnea at rest s/sx of dehydration: marked thirst, poor skin turgor, dry mucous membranes
