Developed circa 1900 and often called the Tallquist Method, it is used to compare a patient's blood colour to a chart of red colours to diagnose possible anaemia. A health care provider takes a patient's blood sample on the perforated, absorbent paper then holds the sample under the holes in the colour chart to decided which colour matches best. Haemoglobin is an iron containing protein that bonds with oxygen and is responsible for making blood red.
This is one of a group of objects once belonging to Francis (Frank) Patrick Morgan (1906 - 1988), neurosurgeon and founder member of the Neurological Society of Australasia.
Frank Morgan served as honorary neurosurgeon at St Vincent's for thirty years until he stepped aside to become assistant neurosurgeon in 1966, although he continued to operate until the age of 79. During this time he served as chairman of the Medical Advisory Committee and the Electoral College and a member of the Advisory Council.
