Cyanotic is the term used to describe the colour of the child's skin in the documentation of failure to collect a specimen.
Cyanosis is characterized by a shift in the colour of human tissues to a bluish-purple tone. This colour change occurs as a consequence of reduced levels of oxygen being attached to the haemoglobin in the RBCs of the capillary bed. The lips, mucous membranes, nail beds, and ear lobes are among the most common areas on the body to exhibit cyanosis as these areas have thinner layers of skin than other parts of the body. In addition to cyanosis, a bluish discolouration of the skin tissue can be caused due to the consumption of food products with blue or purple dyes.
