Albumin I think. The light chains would be found in a urine sample in multiple myeloma in which a patient may present with back pain, malaise, and show monoclonal IgG spike. I don't know about T-H protein or transthyretin, however.

"A" is the response., albumin. Must be.
The other options would need more data.

I'll go with A

You can't detect imunoglobulin chains (light or heavy) with a simple urinalysis and like someone said you'd need more data to rule out the other two. Albuminuria is detactable by simple urinalysis.
