Question

Quizplus · Accepted Answer

A pink color in the supernatant during the Apt test indicates the presence of fetal hemoglobin. This is because the Apt test is designed to differentiate between fetal and maternal hemoglobin in a maternal blood sample, and fetal hemoglobin is more resistant to denaturation by a mild acid solution used in the test, resulting in a pink color in the supernatant.
