Workup
A dermatologist can help in the initial diagnostic workup to determine the cause (Wood's lamp evaluation, biopsy), the extent of lesions, and the presence of extracutaneous manifestations. [statpearls.com]
Laboratory workup revealed haemoglobin 10g/dL, complete blood count including differential count, platelet count, bleeding time and coagulation profile were within normal limits. Random blood glucose level was 46 mg/dL. [indianpediatrics.net]
In the absence of a positive family history for TSC or additional symptoms, further workup is unnecessary.184 5.1 Assessment A suspected diagnosis of Piebaldism or WS should be accompanied by a thorough history and physical examination (Figure 3). [onlinelibrary.wiley.com]
