With all of the modern advancements in forensic equipment, would blood be traceable in a house after 30 or more years?
Assume that the house has been remodeled at least once in that timeline. The murder took place in an area that once had carpet - but was replaced with tile shortly after the crime.
If it is possible to still detect blood, what technique would be used to discover it? (For instance, would luminol still be used?)

I did not kill anyone, by the way. I've been infatuated with Forensic shows recently. (The real ones like on Court TV and the Discovery Channel - not CBS's CSI.)

Luminol typically detects blood on an object's surface, so it wouldn't be detectable on the TILES
Say that the blood had seeped through the original carpet and was absorbed by the underlying floorboards. If those floorboards were tested 30 years later, the blood would probably be detectable. However, if the carpet was pulled up and replaced with tile, that tile would cover the floorboards that absorbed the blood. Because the blood was never on the tile, the luminol wouldn't be able to detect it.
If the investigation team really thought that the house had been the scene of a murder, they could tear up the tile and test the underlying floor -- i'm pretty sure that's the only way the blood could be detectable

Proteins in the blood will have broken down alot. Luminol will most likely have vague results. The best bet would be to do a spectro on a sample from all areas surrounding the scene.

From my understanding of luminol. If there even was a hint of blood it will detect it. Luminol binds to the protients in bloods they last a long time.

I watch cold case files, forensic files, american justice, first 48 religiously. Yes, it could still detect any amount of blood!

If you kill someone and want to protect yourself, best go out of the country and stop making these question.Of course blood is traceable,DNA...dinousars ets.

The blood would be traceable, but the DNA might not be.

If there is any trace of blood left on any surface... it will be able to be traced.
