thanks, Sheldon. I was waiting for your answer… Yes, I had a negative AL test so I’m assuming wild type. Continued prayers for everyone.

Genetic testing for hereditary ATTR otherwise known as hATTR or vATTR, that yields a negative result for all 130 genome responsible for hATTR, may mean that you either have wtATTR or AL Amyloidosis. A Kappa/Lamda blood test and a 24-hour urine test for light proteins can rule out AL Amyloidosis. Then you know with certainty that you have wtATTR.

I have biopsy-proven Cardiac AL. Urine has always been negative, as was fat-pad (abdominal) aspirate.

A negative ATTR gene test does not automatically mean you have wild-type ATTR amyloidosis. Here's a detailed explanation:

- Testing Process
- If a protein sequence analysis test on a biopsy sample shows that the TTR protein is involved, a blood sample is sent for a genetic-sequencing test to examine the DNA chains.

A negative ATTR gene test does not automatically mean you have wild-type ATTR amyloidosis. Here's a detailed explanation:

- Testing Process:
- If a protein sequence analysis test on a biopsy sample shows that the TTR protein is involved, a blood sample is sent for a genetic-sequencing test to examine the DNA chains.
- If this genetic-sequencing test produces no identifiable mutations, then wild-type ATTR amyloidosis is the resulting diagnosis.

- Other Tests:
- Doctors may also perform other laboratory tests, including blood or urine tests, to determine whether the organs are working correctly.
- Certain blood tests may be used to track amyloidosis.

In summary, a negative ATTR gene test is a significant step towards diagnosing wild-type ATTR amyloidosis, but additional tests and evaluations are typically required to confirm the diagnosis.
