Which statement is false regarding blood tests? 1) Dried bloodstains may tentatively be identified as blood by a Luminol test. 2) The Kastle-Meyer test (turns pink) is used to determine whether blood is of human origin. 3) The bonding of an antigen with its specific antibody causes agglutination. 4) All blood contains hemoglobin, which is responsible for oxygen transport.
