Immunohistochemistry p53 Test in UAE | 450 AED | 2026 DHA Guidelines

1. What exactly does a p53 IHC test report tell my oncologist?

Snippet Killer: Your report reveals whether the p53 protein is wild‑type (normal) or mutant‑pattern, which helps classify tumour aggressiveness and predict response to chemotherapy or targeted drugs in breast, ovarian, and gastrointestinal cancers.
A wild‑type pattern typically suggests a functional tumour suppressor, while overexpression or complete absence often correlates with TP53 gene mutation and may indicate eligibility for clinical trials or specific biologics. Your oncologist integrates this with the full pathology report and imaging.

2. How should I prepare for tissue submission to ensure accurate results?

Snippet Killer: You do not need to fast or change medications; simply ensure the formalin‑fixed paraffin‑embedded block (FFPE) or 10% formal‑saline‑preserved biopsy is accompanied by the original histopathology report, biopsy site, and clinical history.
Our logistics team can arrange home collection of the block at room temperature. No special patient preparation is required. For fresh biopsies, the referring physician will handle fixation. Please do not freeze the specimen.

3. Does a mutant p53 result mean I have Li‑Fraumeni syndrome?

Snippet Killer: Not necessarily; somatic p53 mutations are extremely common in sporadic cancers, and a positive IHC alone requires genetic counselling and germline testing to confirm a hereditary cancer syndrome like Li‑Fraumeni.
A mutant IHC pattern in tumour tissue often reflects an acquired somatic change. Only if blood or normal tissue testing reveals the same mutation should a diagnosis of Li‑Fraumeni be considered. Our report includes a clear recommendation for geneticist referral when indicated.
