Histopathology / Biopsy Tissue Examination

Histopathology is the microscopic examination of tissue removed during a biopsy or surgical procedure. Unlike a routine blood test, the specimen is tissue that must be labelled, preserved, transported and processed correctly before a pathologist can examine prepared sections under a microscope.

The type of specimen and the clinical question determine how the laboratory handles it. Some cases may require special stains, immunohistochemistry or additional review. These extra steps can affect turnaround time, so histopathology reporting cannot be treated like a routine same-day blood test.

MultanLab can help coordinate eligible specimen handling or laboratory booking where appropriate, but the diagnostic interpretation is performed by the reporting pathology laboratory. Always follow the surgeon, clinician or laboratory’s specimen instructions because incorrect storage or transport can compromise the sample.

Histopathology is the microscopic examination of tissue removed during a biopsy or surgery. Unlike a routine blood test, it does not usually produce a single numeric ‘normal range’. A pathologist examines the architecture and cells of the specimen and issues a descriptive pathology report with a diagnosis or differential interpretation.

The report may include the specimen type and site, gross description, microscopic findings, final diagnosis and comments. Depending on the tissue and question, additional stains, immunohistochemistry or molecular tests may be needed. Accurate clinical details and correct specimen handling are essential because interpretation depends on where the tissue came from and how it was collected.

Histopathology is requested when a clinician needs microscopic assessment of tissue. This can include biopsies of skin, gastrointestinal tissue, breast tissue or other organs, as well as tissue removed during surgery. The report can describe tissue architecture, inflammation, benign changes, precancerous changes or malignancy when present.

The exact clinical question and specimen site are important, so the laboratory requisition should accompany the sample whenever possible.

A histopathology report is written by a pathologist and can contain descriptive findings, a diagnosis and sometimes comments about margins, grade or recommended ancillary testing, depending on the specimen. The treating clinician interprets the pathology report together with imaging, examination and the procedure findings.

Some cases need additional stains, molecular tests or a second opinion before a final diagnosis is issued.

Histopathology depends on an adequate, correctly handled specimen. A small biopsy samples only part of a lesion, and some diagnoses require correlation with imaging, clinical findings or additional tests.

Histopathology is not a routine home blood collection service. Tissue is obtained by a clinician during biopsy or surgery and placed in the correct container or fixative. The receiving laboratory’s specimen and transport requirements should be confirmed before the procedure when possible.
