hemoglobin (Hb) |
purpose: used to detect iron deficiency anemia increased levels: hemoconcentration due to polycythemia vera or dehydration decreased: anemia, recent hemorrhage, hemodilution from fluid retention Infants (1 – 3days): 14.5 – 22.5 g/dL Infants (2months):9.0 – 14.0 g/dL Children (6 –12 years): 11.5 – 15.5 g/dL Adult Males:14 – 18 g/dL Adult Females:12 – 16 g/dL |
|
|
Hematocrit (HCT) |
Purpose: measure of cell volume; indicates iron status Infants (1 – 3days): 44% - 72% Infants (2months): 28% - 42% Children (6 –12 years): 35% - 45% Adult Males:37% - 49% Adult Females:36% - 46% |
|
|
Low Density Lipoprotein cholesterol (LDL-C) |
purpose: "bad" cholesterol; associated wit increased risk of atherosclerosis and coronary artery disease, major carrier of cholesterol in the blood Abnormal: Levels 200 –239 mg/dL: moderate risk of coronary artery disease Levels >240mg/dL: high risk for coronary artery disease, heart attack, stroke, peripheralvascular disease Children &Adolescents: <110 mg/dL Adults:<130 mg/dL |
|
|
High Density Lipoprotein (HDL-C) |
purpose: good cholesterol; inversely related to coronary artery disease risk Men: 35 – 65mg/dL Women: 35 – 80mg/dL |
|
|
Serum triglycerides (TGs) |
purpose: blood fats; screen for hyperlipidemia and risk for coronary artery disease, age related abnormal: BorderlineHigh: 150 – 199 mg/dLHigh: 200 –499 mg/dL Ages 0 to 19:10 – 100 mg/dL Ages 20 – 65:<150 mg/dL |
|
|
serum proteins (serum albumin) |
purpose: common measurement of visceral protein status; better indicator of long term protein status rather than acute protein malnutrition seen during serious illness abnormal: Low levels dueto protein-calorie malnutrition, altered hydration status, decreased liverfunction. Moderatevisceral protein depletion: 2.8 – 3.5 g/dL Severevisceral protein depletion: <2.8 g/dL Infant (6 mo)– Adult: 3.5 – 5.5 g/dL |
|
|
serum transferrin |
purpose: iron transport protein; measured by total iron binding capacity. more sensitive indicator of visceral protein than albumin abnormal:Mild proteindeficiency: 150 – 170 mg/dL Moderateprotein deficiency: 100 – 150 mg/dLSevere proteindeficiency: <100 mg/dL Range: 170-250 mg/dL |
|
|
Prealbumin |
purpose:Thyroxine-bindingprealbumin; transport protein for thyroxine (T4) &retinol-binding protein. Sensitive to acute changes in protein status andsudden demands on protein synthesis. abnormal: Elevated inrenal disease; reduced by surgery, trauma, burns, & infection. MildDepletion: 10 – 15 mg/dL ModerateDepletion: 5 – 10 mg/dL SevereDepletion: <5 mg/dL Range: 15-25 mg/dL |
|
|
C-reactive protein (CRP) |
purpose: Plasma proteinmarker of inflammatory status produced by liver; used to monitor metabolicstress such as trauma, surgery, or burns and to determine when to beginnutritional support in critically ill patients. Not detectable in healthyindividuals.High-sensitivity CRP (hs-CRP) is used to assessrisk for myocardial infarction. abnormal: Detectablelevels seen in infections, rheumatoid arthritis, or tuberculosis (inflammatoryconditions). Use of oral contraceptives& last 4-5 months of pregnancy can produce detectable levels. Can increaserisk for atherosclerosis <0.1 mg/dL |
