LAB VALUES

Question 1

ALBUMIN

Answer 1

3.5-5 G/DL

LOW: EDEMA, SURGERY

HIGH: DEHYDRATION

MAINTAINS COLLOIDAL OSMOTIC PRESSURE

Question 2

TRANSFERRIN

Answer 2

> 200 MG/DL

1. TRANSPORTS IRON TO BONE MARRROW
2. INCREASED - IRON DEFICIENCY
3. NOT USEFUL FOR PROTEIN STATUS EVALUATION

Question 3

TTHY (TRANSTHYRETIN), PAB (PREALBUMIN)

Answer 3

16-40 MG/DL

1. SHORT HALF-LIFE
2. SHOWS CHANGES IN PROTEIN STATUS

DURING INFLAMMATION LIVER SYNTHESIZES CRP AT EXPENSE OF PAB

Question 4

RPB (RETINOL-BINDING PROTEIN)

Answer 4

3-6 MG/DL

1. SHORTEST HALF-LIFE- 12 HRS
2. CIRCULATES WITH ALBUMIN
3. BINDS AND TRANSPORTS RETINOL

Question 5

Hct (Hematocrit)

Answer 5

men: 42-52%
w: 37-47 %
pregnancy: 33 %
newborn: 44-64%

Question 6

Hgb (Hemoglobin)

Answer 6

men: 14-17 gm/dl
w: 12-15 gm/dl
pregnancy: >= 11

Question 7

Creatinine (serum)

Answer 7

0.6-1.4 mg/dl

1. with BUN- indicators of kidney function
2. indicator of muscle wasting
3. measures somatic protein

Question 8

BUN (Blood Urea Nitrogen)

Answer 8

10-20 mg/dl

1. indicator of renal disease
2. related to protein intake

Question 9

BUN: CREATININE RATIO

Answer 9

NL: 10-15 : 1

Question 10

Urinary creatinine clearance

Answer 10

NL: 115 +- 20 ml/min

1. Measures GFR
   2, indicator of renal function

Question 11

TLC (TOTAL LYMPHOCYTE COUNT)

Answer 11

NL: > 2700 CELLS/CU MM

1. MEASURES IMMUNOCOMPETENCY
2. 900-1800- MODERATE DEPLETION
3. < 900 - SEVERE DEPLETION
4. LOW IN PEM

Question 12

CRP

Answer 12

1. INDICATOR OF ACUTE INFAMMATORY STRESS
2. DECLIINES WITH BENEFICIAL NUTRITION THERAPY

CRP DECLINES, PAB INCREASES
