Movie played on Sci-Fi about people with blue or green blood

Question

I watched this movie on the Sci Fi Channel sometime between 1992 and 1996. It may have been produced in the late 80s. I vaguely remember watching it as a kid but it took place in the desert. It was most likely low budget and may POSSIBLY be based on a novel.

I think that people in a town started to get sick or started disappearing. I remember a teenage kid getting cut on either a vehicle or construction vehicle and his blood was either blue or green. I also remember towards the end of the movie over a hill in a desert I think, there was some sort of bubble pod or containment that was either lit or blue that was holding people from the town. I think that the main protagonist jumped into it? I don’t remember the plot, only smalls bits and pieces. It reminded me of the body snatchers and how people were acting different/getting sick.

Answer 1

Possibly The Andromeda Strain:

After a satellite, a U.S. government project code-named Scoop, crashes near the small rural town of Piedmont, New Mexico, almost all of the town's inhabitants die instantly.

It turns out people are infected with an alien microorganism, which is green and turns their blood into crystals.

There are also bio-isolation installations, both in the town and in the research station tasked with combatting the mircoorganism.
