Advanced Diabetic Package
- Why is it done?
- Comprehensive diabetes screening and monitoring to evaluate glycemic control, pancreatic function, and metabolic status in both newly diagnosed and established diabetic patients
- HbA1c and eAG assess long-term glycemic control over 2-3 months, helping determine if blood sugar targets are being met
- Fasting insulin and C-peptide measure pancreatic beta cell function and insulin secretion capacity to determine insulin resistance and diabetes type
- Kidney profile and microalbumin detect diabetic nephropathy, one of the major microvascular complications of diabetes
- Liver function tests monitor hepatic metabolism and detect diabetes-related fatty liver disease (NAFLD)
- Lipid profile assesses cardiovascular risk factors; dyslipidemia is common in diabetics and increases heart disease risk
- Thyroid profile screens for thyroid disorders, which commonly coexist with diabetes and affect glycemic control
- Pancreatic profile (amylase and lipase) evaluates pancreatic health and screens for acute or chronic pancreatitis
- Complete blood count identifies anemia, infection, or hematologic abnormalities common in diabetic patients
- Iron studies assess iron metabolism and detect hemochromatosis, which can cause secondary diabetes
- Serum electrolytes monitor sodium, potassium, and chloride levels, which are critical in diabetic patients, especially those with kidney disease or taking certain medications
- Recommended for initial diabetes diagnosis confirmation, routine diabetes management, pre-treatment evaluation, and annual comprehensive health assessment in diabetic patients

- Amylase: 30-110 IU/L; elevated in pancreatitis or salivary gland disease
- Lipase: 0-60 IU/L; more specific for pancreatic inflammation than amylase; elevated in pancreatitis
- Hemoglobin: 13.5-17.5 g/dL in males; 12.0-15.5 g/dL in females; <12.0 in females indicates anemia
- Hematocrit: 41-53% in males; 36-46% in females; reflects percentage of red blood cells in total blood volume
- RBC Count: 4.5-5.9 million/mcL in males; 4.1-5.1 million/mcL in females; indicates oxygen-carrying capacity
- WBC Count: 4.5-11.0 thousand/mcL; elevated in infection or inflammation; decreased in bone marrow disorders
- Platelets: 150-400 thousand/mcL; important for blood clotting
- Sodium (Na): 136-145 mEq/L (136-145 mmol/L); critical for fluid balance and nerve function

- Chloride (Cl): 98-107 mEq/L (98-107 mmol/L); maintains acid-base balance and osmotic pressure
- Interpretation
- Microalbumin: <30 mg/24h indicates normal kidney function; 30-300 mg/24h suggests early diabetic nephropathy requiring intervention; >300 mg/24h indicates advanced kidney disease; useful for detecting kidney disease before serum creatinine becomes elevated
- C-Peptide Fasting: Low levels (<0.8 ng/mL) indicate little/no insulin production, suggesting Type 1 diabetes or advanced Type 2 diabetes; elevated levels (>3.1 ng/mL) suggest strong insulin production indicating intact beta cell function; ratios compared with glucose help calculate HOMA-IR for insulin resistance assessment
- Insulin Fasting: Levels >12 mIU/mL suggest insulin resistance, metabolic syndrome, or early Type 2 diabetes; low levels with high glucose indicate inadequate insulin secretion; HOMA-IR (Homeostasis Model Assessment) calculated as (fasting insulin × fasting glucose)/405 with >2.0 indicating insulin resistance; not routinely diagnostic but useful for phenotyping
- Iron: Elevated iron with high transferrin saturation (>50%) suggests hemochromatosis, which can cause secondary diabetes (hemochromatotic diabetes); low iron indicates iron deficiency anemia; high TIBC with low iron suggests iron deficiency; normal TIBC with high iron suggests hemochromatosis
- Albumin: Low albumin (<3.5 g/dL) indicates malnutrition, liver disease, or nephrotic syndrome; in diabetics may reflect malnutrition, liver dysfunction, or protein losses in urine; normal albumin helps maintain colloid osmotic pressure
- ALP Elevation: >120 IU/L may indicate cholestasis, bone disease, hepatic infiltration, or liver dysfunction; in diabetics may suggest metabolic bone disease or fatty liver disease; disproportionate elevation compared to AST/ALT suggests cholestatic pattern
- Bilirubin Elevation: Total >1.2 mg/dL suggests hemolysis, cholestasis, or hepatic dysfunction; elevated indirect fraction indicates hemolysis or impaired uptake; elevated direct fraction indicates cholestasis or hepatocellular injury; in diabetics may reflect fatty liver disease
- AST/ALT Elevation: >40 IU/L for AST or >56 IU/L for ALT suggests hepatocellular injury; AST >ALT pattern suggests chronic liver disease or hemolysis; ALT >AST suggests acute liver injury or fatty liver disease (NAFLD); both elevation indicates hepatitis; AST/ALT ratio used to assess fibrosis
- Total Protein <6.0 g/dL indicates hypoproteinemia from malnutrition, liver disease, or renal losses; >8.3 g/dL suggests dehydration or myeloma; A/G ratio <1.0 indicates globulin excess (infection, autoimmune disease); >2.5 indicates albumin excess or globulin deficiency
- GGT Elevation: >65 IU/L indicates cholestasis, hepatocellular disease, or alcohol-related liver damage; more specific for liver origin than ALP; correlates with oxidative stress and metabolic dysfunction
- BUN Elevation: >20 mg/dL suggests kidney dysfunction, dehydration, or high protein diet; in diabetics indicates declining glomerular filtration; low BUN (<7 mg/dL) suggests malnutrition or liver disease; BUN rises disproportionately in prerenal azotemia (dehydration)
- Creatinine Elevation: >1.3 mg/dL indicates reduced kidney function; in diabetics, even 'normal' creatinine may underestimate kidney disease in elderly or frail patients; creatinine doubles approximately when GFR is halved; rate of rise important for monitoring progression
- eGFR <60 mL/min/1.73m² defines chronic kidney disease Stage 3 or higher; <30 indicates advanced kidney disease requiring specialist management; eGFR >60 with albuminuria still indicates kidney disease; used to adjust drug dosing and monitor progression
- BUN/Creatinine Ratio >20 suggests dehydration, prerenal disease, or GI bleeding; <10 suggests overhydration, liver disease, or malnutrition; ratio helpful in distinguishing prerenal from intrinsic kidney disease
- Urea (equivalent to BUN ÷ 2.8): Elevated urea reflects impaired kidney clearance; used in many countries outside USA; prognostic marker for kidney disease progression
- Calcium <8.5 mg/dL suggests hypocalcemia from vitamin D deficiency, kidney disease, hypoparathyroidism; >10.2 mg/dL indicates hypercalcemia from hyperparathyroidism, malignancy, excess vitamin D; ionized calcium more accurate than total; corrected calcium calculated in hypoalbuminemia
- Uric Acid Elevation: >7.2 mg/dL in males or >6.0 mg/dL in females raises gout risk, metabolic syndrome, kidney disease; in diabetics correlates with insulin resistance and cardiovascular risk; low uric acid (<2.0 mg/dL) suggests xanthine oxidase deficiency or uricosuric drugs
- Total Cholesterol ≥240 mg/dL significantly increases cardiovascular risk in diabetics; 200-239 mg/dL borderline and warrants lifestyle modification; diabetics should aim for <200 mg/dL ideally; level influenced by age, diet, genetics, medications
- LDL >160 mg/dL indicates high cardiovascular risk; diabetics should target LDL <70 mg/dL (very high risk) or <100 mg/dL (standard); LDL particle size and density matter (small dense particles more atherogenic); LDL calculated as (TC - HDL - Triglycerides/5)
- HDL <40 mg/dL in males or <50 mg/dL in females is independent cardiovascular risk factor; each 1 mg/dL increase reduces risk ~2%; higher HDL protective even with elevated LDL; low HDL associated with insulin resistance and metabolic syndrome
- Triglycerides ≥200 mg/dL (2.0 mmol/L) are independent cardiovascular risk factor and associated with small dense LDL; very high triglycerides (≥500 mg/dL) risk acute pancreatitis; triglycerides raised by high carbohydrate diet, obesity, alcohol, poorly controlled diabetes
- VLDL Elevation >40 mg/dL suggests hypertriglyceridemia and metabolic dysfunction; VLDL particles pro-atherogenic; correlates with insulin resistance
- Total/HDL Ratio <5.0 is desirable; >5.0 indicates increased cardiovascular risk; lower ratios with same total cholesterol preferable; important prognostic marker
- LDL/HDL Ratio: Optimal <2.0; 2.0-3.0 desirable; >3.0 indicates increased cardiovascular risk; provides better prognostic value than LDL alone
- Non-HDL >130 mg/dL indicates excess apoB-containing particles (LDL + VLDL); particularly useful when triglycerides elevated as more accurate than LDL; target <130 mg/dL for diabetics
- TSH >4.0 mIU/L suggests primary hypothyroidism; <0.4 mIU/L suggests hyperthyroidism or overtreatment; abnormal TSH with normal free T4 suggests subclinical thyroid disease; hypothyroidism impairs glucose control and increases hypoglycemia risk
- Total T3/T4 Abnormalities: Low T3 syndrome in severe illness; elevated free T3 with low TSH suggests Graves disease; pattern helps differentiate primary thyroid disease from pituitary/hypothalamic disease
- HbA1c ≥6.5% confirms diabetes diagnosis; <5.7% is normal; 5.7-6.4% indicates prediabetes requiring lifestyle intervention; lower HbA1c targets (<7%) recommended for many diabetics to reduce complications; targets individualized by age, duration, and comorbidities; elevated HbA1c despite normal fasting glucose indicates postprandial hyperglycemia
- eAG Interpretation: Calculated as (28.7 × HbA1c) - 46.7 in mg/dL; provides glucose equivalent of HbA1c; eAG 130 mg/dL corresponds approximately to HbA1c 6.5%; useful for patient education; less accurate at extremes of hemoglobin or in hemoglobinopathies
- Amylase Elevation >110 IU/L suggests pancreatitis, though not specific (also elevated in parotitis, intestinal disease); amylase peaks and normalizes within 3-5 days in acute pancreatitis; chronic pancreatitis may have normal amylase; useful for acute presentation
- Lipase Elevation >60 IU/L more specific than amylase for pancreatic injury; elevated longer than amylase (persists 8-14 days); lipase >3× upper limit suggests acute pancreatitis; must be interpreted with clinical presentation and imaging
- Hemoglobin <12 g/dL in females or <13.5 g/dL in males indicates anemia; severity determines clinical significance; mild anemia often asymptomatic but affects oxygen delivery; causes include iron deficiency, B12/folate deficiency, chronic disease, hemolysis
- Hematocrit <36% in females or <41% in males indicates anemia; percent change important for monitoring; rapid decline suggests acute bleeding or hemolysis; gradual decline suggests chronic anemia from nutritional deficiency or chronic disease
- RBC Count <4.1 million/mcL in females or <4.5 million/mcL in males indicates anemia; indices (MCV, MCH, MCHC) determine type (microcytic, normocytic, macrocytic); helpful for etiology of anemia
- WBC >11,000 suggests infection, inflammation, leukemia, or stress; <4,500 indicates leukopenia from bone marrow disease, medications, autoimmune disease; differential count identifies specific leukocyte abnormalities
- Platelets <150,000 indicates thrombocytopenia increasing bleeding risk; >400,000 suggests thrombocytosis from inflammation, myeloproliferation, or iron deficiency; affects wound healing and infection risk
- Sodium <136 mEq/L indicates hyponatremia from SIADH, medication, or dilution; >145 mEq/L indicates hypernatremia from dehydration or inadequate water intake; affects neurologic function, osmolality, and fluid balance
- Potassium <3.5 mEq/L indicates hypokalemia from diuretics, diarrhea, or medications; >5.0 mEq/L indicates hyperkalemia risking arrhythmias and muscle weakness; critical in diabetics on ACE inhibitors/ARBs; affects cardiac conduction
- Chloride <98 mEq/L suggests hypochloremia from vomiting, loop diuretics, or metabolic alkalosis; >107 mEq/L indicates hyperchloremia from diarrhea or metabolic acidosis; maintains electroneutrality

- C-Peptide: If low despite hyperglycemia, confirms Type 1 diabetes or advanced Type 2; if high with elevated glucose, indicates insulin resistance requiring lifestyle intervention and possible pharmacotherapy; can be repeated to track beta cell loss
- Iron Studies: If transferrin saturation >50%, perform liver biopsy or MRI to assess for cirrhosis; screen first-degree relatives; repeat testing annually; if iron deficiency confirmed, investigate for GI bleeding; iron supplementation if deficient; consider phlebotomy if hemochromatosis diagnosed
- Liver Function Tests: If ALT/AST elevated, repeat to confirm; ultrasound or FibroScan to assess fatty liver and fibrosis; if GGT/ALP disproportionately elevated, obtain right upper quadrant ultrasound for biliary obstruction; check viral hepatitis serology if indicated; referral to hepatology if concerning for cirrhosis
- Kidney Profile: If abnormal, repeat in 2-4 weeks to confirm; measure 24-hour urine protein; renal ultrasound if eGFR <30; refer to nephrology if rapid decline or eGFR <30; assess for contrast-induced nephropathy if procedures planned; monitor annually in all diabetics; adjust medication doses for renal function

- Fasting Required?
- YES - Fasting for 8-12 hours is required for the Advanced Diabetic Package
- Fasting Duration: 8-12 hours recommended; ideally 10 hours overnight fasting; 8-10 hours minimum acceptable; longer than 12 hours not necessary and may affect some results
- Fasting Components: No food or calorie-containing beverages; water allowed; black coffee or tea without milk/sugar acceptable; no juice, sports drinks, or energy drinks; avoid chewing gum (contains sugar/non-nutritive sweeteners affecting results)
- Medications: Continue all regular medications unless specifically instructed otherwise; inform phlebotomist of all medications; some medications affect test results (metformin for renal function, lipid-lowering drugs, corticosteroids); discuss with physician if medication effects concern you
- Insulin Administration: Continue insulin injections/infusions as scheduled; do NOT skip doses; inform lab technician if insulin given to allow for proper test interpretation
- Exercise: Avoid strenuous exercise 24 hours before testing; excessive activity can raise liver enzymes and affect glucose results; light activity acceptable
- Alcohol: Avoid alcohol for 24 hours before testing; alcohol affects liver enzymes, lipids, glucose, and electrolytes; interferes with test interpretation
- Stress: Minimize stress before blood draw; stress hormones affect glucose, cortisol, and CBC results; arrive early to reduce testing anxiety
- Timing: Schedule blood draw in morning (7-9 AM) if possible; fasting state most pronounced in early morning; afternoon testing acceptable if 8+ hour fasting maintained
- Urine Microalbumin: May require 24-hour urine collection (confirm with lab); if collecting, start collection in morning after first void (discard), collect all urine for 24 hours, end collection with first morning void next day; refrigerate collection; transport promptly
- Special Circumstances: If diabetic and taking insulin/medications for hypoglycemia, consult physician about testing day management; have carbohydrate source available after testing; women should avoid testing during menstrual cycle if possible (can affect CBC); report fever, infections, or recent illness to phlebotomist
