Indirect Coombs test (ICT) test

Also called ICT, antibody screen, Coombs

Looks for antibodies in your blood that could attack the baby's red cells.

Why it's done

For Rh-negative mothers, usually at the first visit and around 28 weeks.

What a high result can mean

Positive: antibodies are present; your doctor will monitor the baby more closely.
