Reference for the Clinical Components

Disclaimer:

The following descriptions suggest standard nutritional interpretations for the lab values that are featured in the Clinical Component section of the Food Processor SQL software. These interpretations are provided as a brief general reference. They are not intended to be exhaustive or diagnostic, and may not be appropriate for your specific application.

Weight/BP/Meds

BLOOD PRESSURE

• Normal = <120 mm Hg systolic, < 80 mm Hg diastolic
• High = >= 140 mm Hg systolic, >= 90 mm Hg diastolic
• Low = <= 90 mm Hg systolic, <= 60 mm Hg diastolic

Glucose/Protein/Anemia

GLUCOSE

• Venous - blood drawn from a vein
  Normal (fasting) = 70-110 mg/dL
• Capillary - finger stick
  Average (before meal) = 80-120 mg/dL
  Average (2 hours after meal) = 140-160 mg/dL
• HgbA1c - measures average blood glucose over the past 2-3 months\
  Normal = 6-8%
  Good Control = <9%
  Fair Control = 9-12%
  Poor Control = >12%

PROTEIN

• Albumin - most representative of protein status, good long-term monitor
  Normal = 3.5-5.0 g/dL
  Mild depletion = 2.8-3.5 g/dL
  Moderate depletion = 2.1-2.7 g/dL
  Severe depletion = <2.1 g/dL
• Transferrin - monitor of shorter term protein status, also a measure of iron status
  Normal (males) = 215-365 mg/dL
  Normal (females) = 250-380 mg/dL

ANEMIA (iron deficiency, Folate deficiency, B-12 deficiency)

• Hemoglobin - monitor severity of iron deficiency anemia and response to treatmen
  Normal (males) = 14-18 g/dL
  Normal (females) = 12-16 g/dL
• Hematocrit - decreased in iron deficiency, assists in the diagnosis of iron deficiency anemia
  Normal (males) = 42-52%
  Normal (females) = 37-47%
• Iron - measure of the iron bound to transferrin (transport protein)
  Normal (males) = 80-180 ug/dL
  Normal (females) = 60-160 ug/dL
• Ferritin - indicator of available iron stores
  Normal (males) = 12-300 ng/ml
  Normal (females) = 10-150 ng/ml
• TIBC - a direct measure of transferrin
  Normal (males) = 300-400 ug/dL
  Normal (females) = 350-450 ug/dL
• MCV - used to classify anemias
  Normal = 80-95 um3

Other Metabolites Tab

ELECTROLYTES

• Sodium - major extracellular cation, monitor fluid balance, assess renal function
  Normal = 136-145 mEq/L
• Potassium - major intracellular cation, monitor fluid balance, assess renal function
  Normal = 3.5-5.0 mEq/L

CHOLESTEROL

• Total Cholesterol - used to assess risk of coronary heart disease
  Desirable = <200 mg/dL
  Borderline = 200-239 mg/dL
  At risk for CHD = >240mg/dL
• HDL- thought to play a protective role against CHD
  Desirable (male) = >45 mg/dL
  Desirable (female) = >55 mg/dL
  At risk for CHD (M/F) = <35 mg/dL
• LDL- high levels correlate with increased CHD risk
  Desirable = <130 mg/dL
  Borderline = 130-159 mg/dL
  At risk for CHD = >160 mg/dL

MISCELLANEOUS

• Triglycerides - used to determine risk for CHD
  Normal (male) = 40-160 mg/dL
  Normal (female) = 35-135 mg/dL
• ALP (Alkaline Phosphatase) - used to distinguish between liver and bone disease
  Reference Range (adults) = 30-120 U/L
  Reference Range (children) = 40-300 U/L
• AST (Aspartate Amino Transferase, formerly SGOT) - used in diagnosing liver disease
  Normal (adult)= 8-20 U/L
  Normal (infant) = can be 4 times adult
• ALT (Alanine Aminotransferase, formerly SGPT) - used in diagnosing liver disease
  Normal (male) = 10-32 U/L
  Normal (female) = 9-24 U/L
  Normal (infant) = 2 times adult
• BUN (blood urea nitrogen) - used to assess renal function
  Normal = 10-20 mg/dL
• Creatinine - used to evaluate renal function
  Normal (male) = 0.6 - 1.2 mg/dL
  Normal (female) = 0.5 - 1.1 mg/dL
