BRCA I & II Gene

The CA15-3 test is a blood test designed to measure the levels of cancer antigen 15-3 (CA15-3), a protein produced by normal breast cells. Elevated levels of CA15-3 can occur in individuals with certain cancers, particularly advanced or metastatic breast cancer, making it a valuable tumor marker for monitoring disease progression and treatment response. The test involves drawing a small blood sample, which is analyzed to determine CA15-3 levels, typically considered normal at 30 U/mL or less. While useful for tracking advanced breast cancer, the CA15-3 test is not suitable for initial diagnosis or early detection due to its non-specificity and potential elevation in non-cancerous conditions. It is most effective when used alongside other clinical evaluations and diagnostic tests. Despite its limitations, such as variability in results and non-specificity, the CA15-3 test remains an important tool for managing breast cancer, particularly in assessing treatment efficacy and detecting recurrence.

Purpose of the test

The CA15-3 test is a blood test used to monitor breast cancer progression and treatment response. It measures cancer antigen 15-3 levels, a protein produced by breast cells, which can increase in advanced breast cancer. Key points include:

- Elevated Levels: May indicate cancer spread, especially to bones or liver.
- Decreasing Levels: Suggest effective treatment.
- Increasing Levels: Could mean poor treatment response or recurrence.
- Non-Specificity: Elevated levels can occur in non-cancerous conditions.

The test is valuable for monitoring advanced breast cancer but has limitations due to non-specificity and result variability.

Who Should Get Tested

The CA15-3 test is crucial for individuals with advanced breast cancer. It helps monitor cancer progression and treatment response. Key points include:

- Elevated Levels: May indicate cancer spread, especially to bones or liver.
- Decreasing Levels: Suggest effective treatment.
- Increasing Levels: Could mean cancer growth or recurrence.
- Non-Specificity: Elevated levels can also occur in non-cancerous conditions.

The test is not for initial diagnosis or early detection. It’s best used alongside other evaluations due to its limitations, such as non-specificity and result variability.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results is crucial for managing breast cancer effectively. The CA15-3 test measures cancer antigen 15-3 levels in the blood, providing insights into cancer progression and treatment response. Key points include:

- Elevated Levels: May indicate cancer spread, especially to bones or liver.
- Decreasing Levels: Suggest effective treatment.
- Increasing Levels: Could mean poor treatment response or recurrence.
- Non-Specificity: Elevated levels might also occur in non-cancerous conditions.

Always interpret results alongside other clinical evaluations for accurate diagnosis and management.
