Lab Values Flashcards
Hemoglobin normal value
12 -16
if hemoglobin decreased then
cancer, hemolysis, possible nutritional deficiency
platelets normal value
150,000-400,000
if platelets decreased then
leukemia
WBC** normal value
5,000 - 10,000
RBC** normal value
male 4.7 - 6.1 female 4.2-5.4
hematocrit** normal value
male 42-52% female 37-47%
occult blood** normal value
negative (blood in the stool)
CBC and occult blood test **
WBC, RBC, hematocrit, platelets, occult blood
Coagulation Study
platelets, PT, INR, PTT
if low platelets can be because
blood too thin or immune disorder
if platelets too high can be because
assess for blood clots and right dosage of medications
PT normal value
11-12.5 secs
PT is
used for coumadin; made in liver, monitors oral anticoagulation
INR normal value
1.5 - 4.0
INR stands for
international normalized ratio
PTT normal value
60-70 sec
PTT monitors for
heprin
sodium normal value
135-145
low sodium could be related to
dietary intake, may have renal disease, urine becoming more dilute because of fluid intake
potassium normal value
3.5-5.0
chloride normal value
98-106
if chloride is low than
respiratory changes (remember chloride follows Na)
calcium normal value
9.0 - 10.5 (critical 13)
calcium value effected by
age, if have thyroid/parathyroid disease
electrolytes
sodium, potassium, chloride, calcium
lipid study
total cholesterol, lipoproteins, triglycerides, glucose, hemoglobin A1c
total cholesterol normal value
<200, 200-240 is border line, 240 is high
with high cholesterol worry about
coronary heart disease
LDL
low density lipoprotein
HDL
high density lipoprotein
HDL normal values
male >45 female >55
LDL normal values
<130
VLDL
7-32
triglycerides normal values
male 40-160 female 35-135
glucose normal values
normal fasting 70-110, normal >200
hemoglobin A1c normal values
normal 4-5.5% diabetic less than 7%
hemoglobin A1c measures
long term blood sugar, can tell what blood sugar is over 3 months
renal study
BUN, creatine
BUN normal values
10-20
creatinine normal values
male 1.78 - 2.32 female 1.45 - 1.78
urinalysis
appearance, color, pH, protein, specific gravity, glucose, WBC, RBC
urinalysis normal value appearance
clear
urinalysis normal value color
amber yellow
urinalysis normal value pH
4.6 - 8.0 (average 6.0)
urinalysis normal value protein
0-8
protein in urine is
indicator for renal disease
urinalysis normal value specific gravity
1.005 - 1.030
urinalysis normal value glucose
0.3 - 1.7
should not have glucose level unless
renal damage
urinalysis normal value WBC
0-4
urinalysis normal value RBC
<2
White blood cell count
neutrophils, lymphocytes, monocytes, eosinophils, basophils
neutrophil normal value
55-70%
see neutrophil at
1st sign of infection
lymphocytes normal value
20-40%
lymphocytes
fight chronic/acute viral infection
monocyte normal value
2-8%
monocytes
fight infection
eosinophils normal value
1-4%
eosinophils and basophils specific to
allergic reaction
basophils normal value
0.5-1%
