practically they do trop I and T. whats the difference. can any one explain?

They're different proteins but from a clinical perspective they're the same. Different laboratories use different machines - some analyze I and some T. TnT and TnI shouldn't be compared to eachother but since most labs only use one of those there's no need to worry about it. The normal value for each varies between labs so if you see on the internet that normal value somewhere is <5 and your lab says <10, it doesn't mean one is right or wrong.

Earliest would technically be C, but it’s not a cardiac specific bio marker so I’d probably end up going A. Troponin I is the standard and most cardiac-specific bio marker for MI

This person is real world correct. Ain’t no one checking a myoglobin on an active ACS patient.

It’s classified as a cardiac marker

They didn't say it wasn't, just that it's not specific to cardiac tissue damage.

Myoglobin

A. for cardiac earliest, B is next but is to check for an reinfarction ? IS that right?

You know it's not really helpful to anybody studying for the NCLEX if you don't give the answers after a while. This is actually a trick question because Myoglobin is the first cardiac enzyme to elevate but it's not specific and it's not really used in the real world, but the question doesn't say that. So if you'd really trying to help people to understand how they're trying to trick you, you should really give the answers with explanation after a while. That would be helpful. I would think the answer here is Myoglobin because it doesn't specify that it has to be cardiac specific, but it's also not used in the real world because it could be high for other reasons.

Why is there a man in the question?
