Lab Interpretation/ MED SURG

BMP- basic metabolic panel: electrolytes, kidney function

 Glucose

 Calcium

 Sodium

 Potassium

 CO2

 Chloride

 BUN

 Creatinine

CMP- complete metabolic panel: electrolytes, glucose, kidney function, liver function, bilirubin

 CBC- complete blood count: looking at blood volume

 Anticoagulant Therapy Labs- to monitor when taking anticoagulants

Glucose

70-100 normal range

HYPO less than 40mg/dL critical

HYPER greater than 400mg/dL critical

LABS CANNOT READ BLOOD SUGAR ABOVE 999

Calcium CA

8.4-10.2/8.5-10.5 mg/dL normal

less than 7mg/dL critical hypocalcemia

Greater than 12mg/dL critical hypercalcemia

coming from blood stream

important for nerve conduction, coagulation, and muscle contractions

Sodium (NA)

135-145 mEq/L normal

less than 120 mEq/L critical hyponatremia

greater than 160 mEq/L critical hypernatremia

  • low sodium? think about the brain, cellular edema, dehydration

Potassium (K)=heart

3.5-5.3 mEq/L normal

less than 2.5 mEq/L critical hypokalemia

greater than 6.2 mEq/L critical hyperkalemia

DEADLY ARRYTHEMIAS

important for muscle contraction, especially of the heart, and fluid balance

Carbon Dioxide

22-26 mEq/L normal

less than 15mEq/L critical

greater than 40mEq/L critical

Chloride CL

97-107mEq/L normal

less than 80 mEq/L critical

greater than 115mEq/L critical

congestive heart failure-low CL

kidney- low or high CL

Blood Urea Nitrogen BUN): + creatinine = kidneys/function

5-20mg/dL normal

Greater than 100mg/dL critical

high BUN/creatinine = kidney failure

Creatinine CR

Normal Findings: 0.6 – 1.2 mg/dL

Critical Findings: Greater than 7.4mg/dL

Complete Blood Count CBC
- red blood cells

-white blood cells

-hemoglobin

-hemacrit

-platelets

White Blood cell count WBC

4.5-11 normal

less than 2 critical

greater than 30 critical

infection/inflammation

leukocytosis:

continuous antibiotic use:

  • Neutrophil high- bacterial infection

  • neutropenic

  • Lymphocytes high- viral infection/ lymphoma

  • monocytes high- bacterial infection

Red blood cell count RBC

female

3.6-5.1 normal

male

4.2-5.8 normal

polycythemia= too high//could cause stroke

anemia= too low

Hemoglobin HBG

normal findings 12-18 total

female 11.7-15.5 g/dL

male 14-17.3 g/dL

critical less than 6.6 g/dL greater than 20 g/dL

x3 = hemocrit

Hematocrit HCT

Normal Findings:

Female – 36%-48%

Male – 42%-52%

• Critical Findings:

• Less than 19.8%

• Greater than 60%

Platlets PLT

You need platelets to clot

normal 140,000-400,000

critical less than 30,000

critical greater than 1,000,000


if platlets are too low they are at risk for bleeding out

if redblood cells, hematocrit, hemoglobin are too low it means you are NOT at risk for bleeding you already have!


Anticoagulant therapy labs

PT- protothembin time

normal 9-11.7 seconds for blood to clot

critical greater than 27 seconds

INR- International Normalized Ratio

normal 0.9-1.2

critical findings greater than 5

Troponin=heart attack

produced by the heart muscle, only released into blood bloodstream when PT has an MI

normal finding less than 0.05

Brain Natriuretic Peptide BNP

normal less than 100pg/mL

Great measure for congestive heart failure

Magnesium MG

normal 1.6-2.2mg/dL

Critical Findings:

less than 1.2 mg/dL

greater than 4.3 mg/dL

nerve impulses/relaxation

control sodium, potassium, phosphorus absorption

Albumin

normal findings 3.7-5.1m/dL

main protein in the body- produced in the liver

holding fluid in the vascular space

Liver disease: Low albumin it will seep out

LIPID PANEL

Cholesterol, total

• Less than 200 mg/dL

HDL (High Density Lipoprotein) HAPPYGOOD

• Greater than 60 mg/dL

LDL (Low Density Lipoprotein) LOWSYBAD

• Less than 100 mg/dL

Triglycerides

• Less than 150 mg/dL

Thyroid-stimulating hormone TSH

0.4-4.2

tsh = high = hypothyroid

tsh= low = hyperthyroid

Exam 1 ranges for all labs and what they go with

do not have to know the symptoms of high and low

potassium value: roughly 3.5-5
