Lab Values

As outlined by ANCC

TermDefinition
RBC M: 4.3-5.7 million cells/mm3 F: 3.8-5.1 million cells/mm3
HGB M:13.5-17.5g/dL F: 12-16g/dL
HCT M:39-49% F:35-45%
WBC 4.5-11 thousand cells/mm3
leukocyte differential includes basophils, eosinophils, lymphocytes, monocytes, neurtophils-bands, neutrophils segmented
normal range of basophils 0-.075%
normal range of eosinophils 1-3%
normal range of lymphocytes 23-33%
normal range of monocytes 3-7%
normal range of neutrophils-bands 3-5%
normal range of neutrophils-segmented 54-62%
Mean corpuscular hemoglobin (MCH) 25-34pg/cell
MCH concentrated 31-37%Hb/cell
Mean corpuscular volume (MCV) 80-100FL
Platelet count (thrombocytes) 150-450 thousand/mm3
ALT 0-55 units/L
Albumin 3.5-5.5 g/dL
AST 0-50 units/L
bilirubin (total) 0.2-1.2mg/dL
calcium (total) 8.4-10.2mg/dL
CO2 (total) 20-34mEq/L
Chloride 96-112mEq/L
Creatinine M: 0.7-1.3mg/dL F:0.6-1.1 mg/dL
adult glucose 70-105mg/dL
over 60 years glucose 80-115mg/dL
Hemoglobin A1C <6.5
Potassium 3.5-5.1 mEq/L
Protein (total) 6-8.5g/dL
Sodium 136-146mEq/L
TSH 2-10mcU/ml
Free T3 2.3-4.2pg/ml
Free T4 0.7-2.0 pg/ml
Urea Nitrogen/creatinine ratio 12/1 - 20/1
lab results associated with alcohol abuse/dependence increased GGT, increased AST, increased ALT, increased alkaline phosphatase, increased MCV, increased amylase, increased triglycerides decreased platelets
AST/ALT ratio > 2.0, related to alcoholic liver disease
HgbA1c monitors an average of blood sugar over the past 6 weeks.
GGT stands for gamma glutamyl transferase
GGT is used for determining the case of elevated alkaline phosphatase (ALP). indicative of cardiac disease cause.
ALP is alkaline phosphatase and is the first test for biliary disease
These lab values are related to anemia decreased RBCs, Hgb, Hct
erythrocytosis is an increase in RBC
erythrocytosis with intravascular and extracellurlar fluid volume loss could be attributed to: preganancy, burns, diuretics, COPD w hypoxia
increase in WBC can be caused by infection, steroids
decrease in WBC can be related to HIV or clozaril
increase in glucose can be caused by hyperglycemia r/t diabetes
decrease in glucose can be caused by hypoglycemia r/t excessive insulin admin. or secretion, impaired gluconeogenesis, galactosuria, hypothyroidism, infectious sepsis.
increased potassium has a greater risk of this cardiac arrhythmias
hyponatremia can be caused by SSRIs
increased BUN related to decreased GFR and or an increase in tubular reabsoption is associated with diarrhea and vomiting, diaphoresis hypotension, CHF, sepsis, renal insufficiency, etc.
BUN:Cr Ratio >10:1 preserved GFR
A decrease in BUN can be related to low protein diet, muscle wasting, starvation, cirrhosis, high urine flow
If BUN:Cr ratio is <10:1 it could mean a decrease in urea production, associated with low protein intake, severe diarrhea and vomiting and hepatic insufficiency.
hypernatremia related to total body water deficit with water loss is greater than sodium loss associated with diabetes, vomiting and diarrhea, diuresis, endocrine DOs
hyponatremia related to relative total body water excess can be associated with excess water ingestion or inability of kidneys to excrete sufficiently dilute urine. CHF, cirrhosis with ascites, fluid and electrolyte loss and meningitis.
