Lab Report Analysis - Mathurbhai Pateliya, 50 yr Male (25/06/2026)

Summary of Abnormal Values

Diagnosis: Jaundice with predominant Conjugated (Direct) Hyperbilirubinemia

Most Likely: Hepatocellular Jaundice (acute hepatitis pattern)

• Direct bilirubin = 8.4 mg/dL out of total 9.8 mg/dL = ~86% conjugated
• This is a classic conjugated/direct hyperbilirubinemia (conjugated >30% of total = conjugated hyperbilirubinemia by definition)
• Urine bile pigments and bile salts are both PRESENT - this confirms conjugated bilirubin is spilling into urine, as only conjugated bilirubin is water-soluble and can be excreted renally

• Per Quick Compendium of Clinical Pathology: in hepatocellular jaundice, transaminases are >3x ULN, while in cholestatic jaundice they are <3x ULN
• This patient is at 2.7x ULN - borderline but strongly suggesting a hepatocellular/mixed pattern
• Notably, alkaline phosphatase is NOT reported here; if ALP were markedly elevated (>3x ULN), obstructive/cholestatic jaundice would be favored

• Acute viral hepatitis (hepatitis A, B, E most likely in India) - most probable given age, moderate transaminase rise, and degree of bilirubinemia
• Drug-induced liver injury (DILI)
• Alcoholic hepatitis
• Biliary obstruction (gallstone, stricture, malignancy) - less favored without markedly elevated ALP, but cannot be excluded without imaging

Haematological Findings

• Mild normocytic/normochromic anaemia: Hb 12 g%, RBC 3.75, PCV 36.2%, MCV 96.5 fL (normal), MCH 32 pg (borderline high), MCHC 33.15% (normal)
  • This is anaemia of chronic disease or anaemia secondary to liver disease - the MCV is at the upper limit of normal, which can occur in liver disease due to macrocytosis from alcohol or folate deficiency
  • No haemolysis pattern (indirect bilirubin is only mildly elevated relative to direct)
• WBC 9,000/cmm - within normal limits
• Neutrophilia 76% - mild, may suggest bacterial infection, cholangitis, or stress response
• Lymphocytes 19% - relatively low; viral hepatitis often causes lymphocytosis in early stages

Urine Analysis - Key Findings

• Bile pigments: PRESENT (+) - confirms conjugated bilirubin in urine (bilirubin is NOT present in normal urine; only conjugated bilirubin passes the renal filter)
• Bile salts: PRESENT (+) - corroborates obstructed bile flow or hepatocellular damage causing bile regurgitation
• Sugar: ABSENT - rules out diabetes
• Albumin: ABSENT - rules out nephrotic syndrome
• Microscopy: Normal - no RBCs, casts, or significant pyuria

Clinical Interpretation Summary

Recommended Further Investigations

1. Liver Function Tests (full panel): ALP, GGT, albumin, total protein, PT/INR
2. Viral hepatitis serology: HBsAg, Anti-HCV, Anti-HAV IgM, Anti-HEV IgM
3. Abdominal Ultrasound - to exclude biliary obstruction (stones, tumour, ductal dilatation)
4. CBC with peripheral smear - to better characterize anaemia
5. LDH, reticulocyte count - to exclude haemolysis

Note: This analysis is based on available lab values. A clinical examination and full history (alcohol use, medications, fever, pain) are essential for a definitive diagnosis. Please consult the treating physician.
