What this test measures
Tissue specimens collected by punch biopsy (skin), pinch biopsy (endoscopic mucosal sampling), core needle biopsy (radiology-guided breast, liver, kidney, prostate), or shave biopsy. Tissue is fixed in 10% formalin, processed, embedded in paraffin, sectioned, stained (H&E ± special stains / IHC), and examined microscopically by a pathologist. Diagnoses range from confirmation of benign skin lesions to staging of solid tumours and identification of inflammatory / infectious / dysplastic patterns.
Why it matters
Small biopsies are the workhorse of dermatology, GI endoscopy, breast imaging, prostate biopsy, and liver / kidney clinical investigation in India. They balance diagnostic yield with patient burden — outpatient, minimal sedation, fast healing. Histopath of small samples can definitively diagnose: skin malignancies (BCC, SCC, melanoma), inflammatory dermatoses, coeliac disease, IBD, gastritis (H. pylori), early breast cancer, prostate cancer, chronic liver disease (NASH, hepatitis staging), and many more.
How to prepare
Procedure-specific — skin punch usually local anaesthetic; endoscopic biopsy under sedation; image-guided core biopsy with local anaesthetic. Disclose anticoagulation (warfarin, DOACs, antiplatelet — may need to hold or bridge depending on biopsy site), allergies (local anaesthetic, latex), and current infections.
Markers & reference ranges
Reference ranges below are typical adult values. Your lab's reported range may differ slightly based on the assay platform and patient demographics — always read your report against the range printed on it.
| Marker | Normal range | If low | If high |
|---|---|---|---|
| Histopathology Diagnosis (Descriptive)[1][2] | Benign / Negative for malignancy | Benign — no malignancy seen. Specific benign diagnosis (e.g., seborrhoeic keratosis, fibroadenoma, hyperplastic polyp) guides management. | Inflammatory / dysplastic / malignant — diagnosis specifies the entity (e.g., chronic gastritis with H. pylori, ulcerative colitis, basal cell carcinoma, ductal carcinoma in situ, invasive ductal carcinoma, etc.). Tumour samples often need additional IHC for receptor status (breast: ER/PR/HER-2; prostate: PSA), molecular markers, or grade / stage information. |
Common small biopsy sources + uses
| Source | Specimen | Common diagnoses |
|---|---|---|
| Skin punch | 3-6 mm | BCC, SCC, melanoma, inflammatory dermatoses |
| Endoscopic GI | 2-5 mm | Gastritis, IBD, coeliac, early cancer |
| Image-guided breast core | 14-18 gauge cores | Breast cancer, DCIS, atypia |
| Prostate TRUS core | 12-cores | Adenocarcinoma, grade by Gleason |
| Liver core | 14-16 gauge | NASH, chronic hepatitis, cirrhosis grading |
| Renal core | 14-18 gauge | Glomerulonephritis, IgAN, AKI workup |
Frequently asked questions
How long does the report take?
Typically 3-7 working days for routine cases. Urgent (frozen section) or complex cases (additional IHC, molecular) may take longer.
What does "small" specimen mean for fees?
Indian pathology pricing often distinguishes small (≤ 1 cm), medium, and large specimens, reflecting processing complexity (more blocks, sections). All sizes follow the same diagnostic standards.
Do I need to fast?
Depends on biopsy method — skin punch no, endoscopic biopsy usually yes (6-8h fast), core liver biopsy usually 4-6h fast. Follow procedural instructions.
Will I need a follow-up biopsy?
Sometimes — small biopsies may not sample the most diagnostic area. Pathologist may recommend larger / repeat biopsy for definitive diagnosis (e.g., melanoma needing wider excision, lymphoma needing core or excisional).
What is IHC?
Immunohistochemistry — staining tissue with antibodies to identify specific proteins. Used to confirm tumour origin, hormone receptors, infectious agents, etc.
Can the report be wrong?
Pathology is highly accurate but not infallible. Second opinions are reasonable for complex / unusual diagnoses, especially before major treatment (cancer surgery, immunosuppression).
