IMMUNOHISTOCHEMISTRY, BER-EP4 (EPCAM)

The Immunohistochemistry (IHC) – BER-EP4 (EpCAM) test is a specialized diagnostic test used to detect Epithelial Cell Adhesion Molecule (EpCAM) expression in tissue samples. BER-EP4 is a monoclonal antibody widely used in pathology to identify epithelial-derived cells and assist in the diagnosis and classification of epithelial tumors.

EpCAM is a cell surface glycoprotein involved in cell adhesion, proliferation, and differentiation. It is strongly expressed in many epithelial tissues and epithelial-derived cancers. Detecting BER-EP4 positivity helps pathologists distinguish epithelial tumors from non-epithelial lesions and supports accurate tumor classification.

This test is especially valuable in differentiating basal cell carcinoma (BCC) from squamous cell carcinoma (SCC) and other skin lesions. BER-EP4 is usually positive in basal cell carcinoma and negative in most squamous cell carcinomas, making it highly useful for skin tumor diagnosis.

The BER-EP4 marker is also useful in identifying adenocarcinomas, metastatic epithelial tumors, mesothelioma differentiation, and other carcinoma subtypes. It is commonly performed alongside markers such as EMA, CK7, CK20, p63, calretinin, and CEA for enhanced diagnostic accuracy.

Benefits of the Test

The BER-EP4 (EpCAM) test offers several important clinical benefits:

• Detects epithelial cell marker expression accurately
• Helps classify epithelial tumors
• Differentiates basal cell carcinoma from squamous lesions
• Assists in metastatic tumor identification
• Improves diagnostic precision
• Supports treatment planning

This test is essential for accurate epithelial tumor diagnosis.

Why Doctors Recommend This Test

Doctors recommend the BER-EP4 test when epithelial tumor diagnosis or classification requires confirmation.

It is commonly advised for:

• Skin lesion evaluation
• Differentiation of basal and squamous cell carcinoma
• Identification of epithelial-origin tumors
• Metastatic carcinoma classification
• Complex pathology confirmation cases

The results help pathologists provide accurate diagnosis and support clinical decision-making.

Preparation Before Test

No special preparation is required from the patient. The test is performed on previously collected tissue biopsy or surgical specimens.

Normal Reporting Time

The usual turnaround time for the BER-EP4 IHC test is 2 to 5 working days, depending on tissue complexity and laboratory workflow.

Who Should Take This Test

This test is recommended for:

• Patients with suspicious skin lesions
• Individuals suspected of epithelial tumors
• Patients requiring tumor origin classification
• Cases needing metastatic lesion evaluation
• Oncology patients requiring accurate tissue diagnosis

The IHC BER-EP4 (EpCAM) test is an important pathology tool for epithelial tumor diagnosis. It supports precise tissue classification, improves diagnostic confidence, and helps guide effective treatment planning.
