Galleri test - 可以检测50多种癌症并预测起源

我们去年十月份做的。今年还会做，不仅安心而且为决定来年的医疗保险多了一个data point.

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.
