Test
Normal Values* (Adult)
Clinical SigniF
cance
Sedimentation rate, erythrocyte
(whole blood)
Men: 1–13 mm/hr
Women: 1–20 mm/hr
Values increase in infectious diseases, menstruation, pregnancy, and as a result of severe
tissue damage.
Serum glutamic pyruvic
transaminase (SGPT)
Men: 6–24 U/L
Women: 4–17 U/L
Values increase in liver disease, pancreatitis, and acute myocardial infarction.
Sodium (serum)
135–145 mEq/L
Values increase in nephritis and severe dehydration. They decrease in Addison disease,
myxedema, kidney disease, and diarrhea.
Thromboplastin time, partial
(plasma)
35–45 sec
Values increase in deF
ciencies of blood factors VIII, IX, and X.
Thyroid-stimulating hormone (TSH)
0.5–5.0 µU/mL
Values increase in hypothyroidism and decrease in hyperthyroidism.
Thyroxine, or T
4
(serum)
4–12 µg/100 mL
Values increase in hyperthyroidism and pregnancy. They decrease in hypothyroidism.
Transaminases, or SGOT (serum)
7–27 units/mL
Values increase in myocardial infarction, liver disease, and diseases of skeletal muscles.
Triglycerides
40–150 mg/100 mL
Values increase in liver disease, nephrotic syndrome, hypothyroidism, and pancreatitis.
They decrease in malnutrition and hyperthyroidism.
Triiodothyronine, or T
3
(serum)
75–195 ng/100 mL
Values increase in hyperthyroidism and decrease in hypothyroidism.
Uric acid (serum)
Men: 2.5–8.0 mg/100 mL
Women: 1.5–6.0 mg/100 mL
Values increase in gout, leukemia, pneumonia, toxemia of pregnancy, and as a result of
severe tissue damage.
White blood cell count, di±
erential
(whole blood)
Neutrophils 54–62%
Eosinophils 1–3%
Basophils <1%
Lymphocytes 25–33%
Monocytes 3–7%
Neutrophils increase in bacterial diseases; lymphocytes and monocytes increase in viral
diseases; eosinophils increase in collagen diseases, allergies, and in the presence of
intestinal parasites.
White blood cell count, total
(whole blood)
4,500–10,000/µL
Values increase in acute infections, acute leukemia, and following menstruation. They
decrease in aplastic anemia and as a result of drug toxicity.
*These values may vary with hospital, physician, and type of equipment used to make measurements.
