What do positive results mean?

Positive results may indicate mutations in the KRAS gene, which could affect treatment options.

Can the results be negative despite symptoms?

Yes, some cases may occur without KRAS mutations, so it's important to monitor symptoms with a doctor.

Does the analysis affect treatment options?

Yes, the analysis helps guide treatment options, especially targeted therapies.

About this service

The KRAS test (KRAS Gene Analysis) is a genetic test used to detect mutations in the KRAS gene, which plays a crucial role in regulating cell growth and proliferation. This test is an important tool in evaluating certain types of cancer, such as colorectal cancer and lung cancer, as mutations in this gene can help determine the most appropriate treatment options. The analysis is typically performed on a tumor tissue sample or a blood sample and helps doctors understand the nature of the cancer and how the patient may respond to targeted therapy. By identifying the presence of mutations, doctors can make informed decisions about treatment strategies, contributing to improved therapeutic outcomes for patients.

Purpose Test

Genetic mutations: Identifies mutations in the KRAS gene, which are important indicators in certain cancers, such as colon and lung cancer.
Treatment response prediction: Helps evaluate the effectiveness of targeted therapies, as mutations may determine whether the treatment will be successful.
Cancer diagnosis: Can assist in confirming the diagnosis of certain tumor types.

Recommended groups

Patients diagnosed with colon cancer: To identify mutations that may influence treatment options.
Patients with non-small cell lung cancer: The test helps guide targeted therapy.
Individuals with other types of cancer: Such as pancreatic cancer, where KRAS mutations may be associated with disease progression.
Patients undergoing chemotherapy: To assess the potential effectiveness of targeted therapies based on the gene status.

Symptoms indicative

Colon cancer symptoms: Such as rectal bleeding, abdominal pain, and changes in bowel habits.
Lung cancer symptoms: Such as persistent cough, shortness of breath, and unexplained weight loss.
Pancreatic cancer symptoms: Such as upper abdominal pain, loss of appetite, and jaundice.
Family history of cancer: Especially if there is a history of cancers associated with the KRAS gene.

Normal Levels

KRAS analysis does not determine traditional “normal” levels; it focuses on the presence or absence of mutations in the gene.
Results: Positive: KRAS gene mutations are present. Negative: No mutations detected.
Positive: KRAS gene mutations are present.
Negative: No mutations detected.
Interpreting results: Negative result: No mutations found, which may indicate different treatment options. Positive result: Mutations are present, potentially influencing the treatment plan and determining suitable targeted therapies.
Negative result: No mutations found, which may indicate different treatment options.
Positive result: Mutations are present, potentially influencing the treatment plan and determining suitable targeted therapies.
