1

Glucose

79-99 mg/dL

2

Sodium

136-145 mmol/dL

3

Sodium

BOTH: Decreased level of consciousness (confusion, lethargy, coma)

High: perhaps thirst, seizures if develops rapidly or is very severe.

Low: seizures if develops rapidly or is very severe. Aka. Water intoxication; water excess

4

Potassium

3.5-5.1 mmol/dL

5

Potassium

BOTH: Bil. Muscle weakness; dysrhythmias;

High: transient abdominal cramps, diarrhea, cardiac arrest if severe- ECG abnormalities

Low: resp. muscle weakness, abdominal distention, decreased bowel sounds, constipation

6

Calcium

8.2-10.2 mmol/dL

7

Calcium

High: Anorexia, nausea and vomiting, constipation, fatigue, diminished reflexes, lethargy, decreased level of consciousness, confusion, personality change, cardiac arrest if severe

Low: Numbness and tingling of fingers, toes, and circumoral (around mouth) region, positive Chvostek's sign (contraction of facial muscles when facial nerve is tapped), hyperactive reflexes, muscle twitching and cramping; carpal and pedal spasms, tetany, seizures, laryngospasm, dysrhythmias.

8

Chloride

(follows Na+)

98-107 mmol/dL

9

Chloride

(follows Na+)

High: dehydration, problems that cause high sodium- kidney dz, Cushing syndrome.

Low: occurs w/ low sodium- CHF, vomiting, gastric suction, chronic lung dz- resp. acidosis

10

urine chloride

urine chloride High: indicates dehydration, starvation, Addison disease, or increased salt intake. If both chloride and sodium levels are high- not following low Na diet.

urine chloride Low: can be seen with Cushing syndrome, Conn syndrome, congestive heart failure, malabsorption syndrome, and diarrhea.

11

Phosphate

2.4-4.5

12

Phosphate

Like calcium, found in bones and teeth

High: Kidney dz decreases excretion of excess phosphate in blood. Extra can cause calcium to be pulled out of bones.

Low: meds prevent absorption, low mag (needed to absorb), high calcium (binds to), certain breathing problems.

13

CO2

(carbon dioxide combing power)

22-32 mmol/dL

14

CO2

(carbon dioxide combing power)

Serum co2 acts as a bicarbonate (HCO3) determinate. When CO2 is low- HCO3 is lost and acidosis results; When CO2 is high- HCO3 is saved and alkalosis results.

High: Metabolic alkalosis, severe vomiting, gastric suction, peptic ulcer, hypothyroid, potassium deficit, emphysema (hypoventilation) Drugs: Barbiturates, steroids, diuretics.

Low: Metabolic acidosis, diabetic ketoacidosis, starvation, severe diarrhea, dehydration, shock, acute renal failure, exercise. Drugs: diuretics, antibiotics.

15

BUN

(blood urea nitrogen)

5-25 mg/dL

16

BUN

(blood urea nitrogen)

Urea is the product of protein metabolism and is excreted by kidneys.

High: dehydration, prerenal failure, minimally age, digested blood from GI bleeding.

Low: usually indicated overhydration (hypervolemia)

17

Creatinine

(Cr)

0.5-1.5 mg/dL

18

Creatinine

(Cr)

Cr is biproduct of muscle metabolism; Cr is filtered by glomeruli & excreted in urine.

High: acute or chronic renal failure, shock, lupus, certain cancer, leukemia, HTN, MI, heart failure, Cr rich diet (beef). Low: pregnancy, eclampsia; minimal in elderly

19

GFR

>60

20

Total Protein

6.4-8.2 g/dL

21

Total Protein

Your body needs these proteins to fight infections and to perform other functions. Lower-than-normal levels of albumin and total protein might indicate liver damage or disease.

22

Albumin

3.2-4.7 g/dL

23

Albumin

Protein made by liver

24

Total Bilirubin

<1.1

25

Total Bilirubin

substance produced during the normal breakdown of red blood cell

Bilirubin passes through the liver and is excreted in stool. Elevated levels of bilirubin (jaundice) might indicate liver damage or disease or certain types of anemia.

26

*Alkaline Phosphatase

26-137 U/L

27

*Alkaline Phosphatase

enzyme in the liver, bile ducts and bone.

High: may indicate liver damage or disease, such as a blocked bile duct, or certain bone diseases

28

AST

0-37 U/L

29

AST

enzyme that helps metabolize alanine, an amino acid

High: may indicate liver damage or disease or muscle damage

Low: normal and expected

30

ALT

15-65 U/L

31

ALT

enzyme found in the liver that helps your body metabolize protein

High: When the liver is damaged, ALT is released into the bloodstream and levels increase

Low: normal and expected

32

*GGT (Gamma-glutamyltransferase)

9-48 U/L

33

*GGT (Gamma-glutamyltransferase)

Enzyme in the blood

High: may indicate liver or bile duct damage; elevated alkaline phosphatase (ALP) and GGT are elevated in disease of the bile ducts and in some liver diseases, but only ALP will be elevated in bone disease. Low: may indicate a magnesium deficiency
