1
Q
ALBUMIN
A
3.5-5 G/DL
LOW: EDEMA, SURGERY
HIGH: DEHYDRATION
MAINTAINS COLLOIDAL OSMOTIC PRESSURE
2
Q
TRANSFERRIN
A
> 200 MG/DL
- TRANSPORTS IRON TO BONE MARRROW
- INCREASED - IRON DEFICIENCY
- NOT USEFUL FOR PROTEIN STATUS EVALUATION
3
Q
TTHY (TRANSTHYRETIN), PAB (PREALBUMIN)
A
16-40 MG/DL
- SHORT HALF-LIFE
- SHOWS CHANGES IN PROTEIN STATUS
DURING INFLAMMATION LIVER SYNTHESIZES CRP AT EXPENSE OF PAB
4
Q
RPB (RETINOL-BINDING PROTEIN)
A
3-6 MG/DL
- SHORTEST HALF-LIFE- 12 HRS
- CIRCULATES WITH ALBUMIN
- BINDS AND TRANSPORTS RETINOL
5
Q
Hct (Hematocrit)
A
men: 42-52%
w: 37-47 %
pregnancy: 33 %
newborn: 44-64%
6
Q
Hgb (Hemoglobin)
A
men: 14-17 gm/dl
w: 12-15 gm/dl
pregnancy: >= 11
7
Q
Creatinine (serum)
A
0.6-1.4 mg/dl
- with BUN- indicators of kidney function
- indicator of muscle wasting
- measures somatic protein
8
Q
BUN (Blood Urea Nitrogen)
A
10-20 mg/dl
- indicator of renal disease
- related to protein intake
9
Q
BUN: CREATININE RATIO
A
NL: 10-15 : 1
10
Q
Urinary creatinine clearance
A
NL: 115 +- 20 ml/min
- Measures GFR
2, indicator of renal function
11
Q
TLC (TOTAL LYMPHOCYTE COUNT)
A
NL: > 2700 CELLS/CU MM
- MEASURES IMMUNOCOMPETENCY
- 900-1800- MODERATE DEPLETION
- < 900 - SEVERE DEPLETION
- LOW IN PEM
12
Q
CRP
A
- INDICATOR OF ACUTE INFAMMATORY STRESS
- DECLIINES WITH BENEFICIAL NUTRITION THERAPY
CRP DECLINES, PAB INCREASES
