Among all elements which occur in nature; Cobalt is one which when consumed in right amount has many positive effects on human health. Though its overexposure because of absorption, breathing, or skin contact can be hazardous to an individual's health, but the deficiency of it is also not suggested. Individuals working in industries that use products having cobalt have the most exposure to it. Based upon the form of contact, an individual can show symptoms like Dyspnea aka breathing complications, coughing, heart problems, nerve injury and skin irritation. To check the level of Cobalt in the body, it is recommended to go for Cobalt Blood Testing. It is usually prescribed when an individual considers his/her exposure to Cobalt, mainly when their workplace environments have the presence of Cobalt. Although, CBT is also suggested for monitoring blood Cobalt levels for someone at the risk of contact albeit not undergoing symptoms.
