The PIK3CA test is a genetic test for detecting any kind of abnormal behavior in the PIK3A gene.
What is PIK3CA?
PIK3CA is a mutation analysis test to detect abnormalities in the PIK3A gene for diagnosing cancer.
Why is PIK3CA suggested?
Your doctor will ask you to get a PIK3CA test in case you have developed
- Red and firm nodules.
- Pain in the bones.
- Face, arm, or neck swelling.
- Headaches, dizziness, weakness, or numbness in the limbs.

- A rough and scaly patch on the lip that can develop into an open sore.
- Red sores or patches inside the mouth.
- Any red or swollen sore in the anus or in the genital area.
How is PIK3CA performed?
The PIK3CA test is done using a variety of methods including
- The In-situ hybridization technique.
- Next-generation sequencing.
- Polymerase chain reaction.
- Comparative genomic hybridization.
- Karyotyping (including spectral karyotyping).
- mRNA analysis.
- Tissue microarrays.
- Southern blot test.
- Northern blot test.
- Western blot test.
- Eastern blot test.
This is how a PIK3CA test is performed.
What are the parameters measured in PIK3CA?
The PIK3CA test is performed on:
- A fresh tumor during biopsy.
- Solid tumor tissue that has been treated with formalin and embedded in paraffin.
- Unstained tissue slides.
The test process differs across laboratories.
Preparation before performing PIK3CA
There is no special preparation necessary for a PIK3CA test.
Post-care after PIK3CA
There is no post-care necessary after PIK3CA test.
Sample types in PIK3CA
The sample type in PIK3CA test is a tissue sample.

Side effects/risks of PIK3CA
Certain medications may influence the results of the PIK3CA test. You should inform your doctor about all the medicines that you are consuming to avoid a wrong diagnosis.
