AI Overview
The Galleri test is a blood test designed to detect a signal of cancer presence and predict its origin, potentially aiding in early cancer detection. It screens for DNA fragments shed by cancer cells into the bloodstream, acting as a "fingerprint" of cancer. The test can detect over 50 types of cancer, including many deadly ones. It's not a diagnostic test, and further confirmatory testing is needed if a cancer signal is detected.
Here's a more detailed breakdown:
What it is:
The Galleri test is a multi-cancer early detection blood test that analyzes cell-free DNA (cfDNA) in the blood to identify cancer signals.
How it works:
It detects DNA fragments that cancer cells release into the bloodstream when they die, effectively acting as a fingerprint for cancer.
What it detects:
The test can detect a signal from over 50 types of cancer, including many that are difficult to screen for with traditional methods.
What it doesn't do:
It's not a diagnostic test, meaning it doesn't confirm the presence of cancer. If a cancer signal is detected, further diagnostic tests (like imaging) are needed.
Cost:
The Galleri test typically costs around $949, according to the American Academy of Family Physicians.
Availability:
The Galleri test is available by prescription only, and your healthcare provider can order it or you can request it through their website.
Who it's for:
It's recommended for adults with an elevated risk of cancer, such as those aged 50 or older.
Limitations:
The test has a positive predictive value (PPV) of 43.1%, meaning that about 4 out of 10 individuals with a "Cancer Signal Detected" result will have a confirmed cancer diagnosis after further testing. False positive and false negative results can occur.
In summary, the Galleri test is a promising tool for early cancer detection, but it's important to understand its limitations and to follow up with your doctor for any necessary diagnostic procedures.
