Here are standard adult reference ranges for a healthy 28-year-old male, compiled from major medical textbooks in the library (Guyton & Hall, Robbins Basic Pathology, Harrison's Internal Medicine, Textbook of Family Medicine). Note: exact cutoffs vary slightly by lab/analyzer, so always check the "reference range" column printed on your actual report alongside these.
1. CBC (Complete Blood Count)

| MCV | 80-100 fL |
| MCH | 27-33 pg |
| MCHC | 32-36 g/dL |
| WBC (Total count) | 4,000-11,000 /mm³ |

| Lymphocytes | 20-45% |
| Monocytes | 2-10% |
| Eosinophils | 1-6% |
| Basophils | 0-1% |
| Platelet count | 150,000-450,000 /mm³ |
2. RFT (Renal Function Test)
| Parameter | Normal Range |
|---|
| Blood Urea Nitrogen (BUN) | 8-24 mg/dL (males) |
| Blood Urea | ~15-40 mg/dL |
| Serum Creatinine | 0.7-1.3 mg/dL (males) |
| BUN/Creatinine ratio | 10:1-15:1 |
| Sodium (Na+) | 135-145 mmol/L |
| Potassium (K+) | 3.5-5.3 mmol/L |
| Chloride (Cl-) | 98-107 mmol/L |
| Bicarbonate (HCO3-) | 22-29 mEq/L |
| Uric acid | 3.4-7.0 mg/dL (males) |
| eGFR | >90 mL/min/1.73m² |

3. LFT (Liver Function Test)
| Parameter | Normal Range |
|---|
| Total Bilirubin | 0.2-1.0 mg/dL |
| Direct (Conjugated) Bilirubin | 0-0.3 mg/dL |
| ALT (SGPT) | 5-30 U/L (up to ~40-50 U/L per some labs) |
| AST (SGOT) | 10-30 U/L (up to ~40 U/L per some labs) |
| Alkaline Phosphatase (ALP) | 38-126 U/L (males) |
| Total Protein | 6.0-8.3 g/dL |
| Albumin | 3.5-5.5 g/dL |
| Globulin | 2.3-3.5 g/dL |
| GGT | 8-61 U/L (males) |

4. Lipid Profile (Adult, fasting)
| Parameter | Desirable/Normal |
|---|
| Total Cholesterol | <200 mg/dL |
| LDL Cholesterol | <100 mg/dL (optimal) |
| HDL Cholesterol | >40 mg/dL (men) |
| Triglycerides | <150 mg/dL |
| VLDL | 2-30 mg/dL |
| Total Cholesterol/HDL ratio | <5 |

Note on Serology
"Serology" isn't a single fixed panel — it depends on what's being tested (HIV, HBsAg, anti-HCV, VDRL/RPR, dengue, typhoid Widal, etc.). For all standard infectious serology screens (HIV 1&2, HBsAg, Anti-HCV, VDRL), a normal/healthy result is reported simply as "Non-reactive" / "Negative." There's no numeric range — let me know if you want ranges for a specific serology test (e.g., quantitative HBsAg titer, ASO titer, CRP).
If you want, I can also build these into a clean reference sheet (Word/PDF/Excel) for personal use — just say which format.
