In brief: Yes
Screening tests are measurements of certain hormones/proteins in your blood.
They are not diagnostic of chromosomal problems but they do indicate if you are at higher risk and whether you should be offered further diagnostic testing. Different tests have different detection rates and which one you receive will depend on your doctor's office resources/laboratory. Discuss this with your doctor.

In brief: To a degree
The definitive testing involves chromosomes to look at the chromosome 21.
Alphafetal protein levels may be elevated, but just suggest risk. Fetal ultrasounds may also suggest risk. Chromosome testing is definitive.
