Final answer:
The combination of severe eczema, petechiae, and recurrent ear infections in a 18-month-old male is concerning for a condition called Wiskott-Aldrich syndrome (WAS). Patients with WAS often present with symptoms such as easy bruising, bleeding, recurrent infections, and eczema. An immunoglobulin (Ig) panel can be performed to diagnose Wiskott-Aldrich syndrome.
Step-by-step explanation:
The combination of severe eczema, petechiae, and recurrent ear infections in a 18-month-old male is concerning for a condition called Wiskott-Aldrich syndrome (WAS). WAS is a rare genetic disorder characterized by immune system dysfunction. Patients with WAS often present with symptoms such as easy bruising, bleeding, recurrent infections, and eczema.
To diagnose Wiskott-Aldrich syndrome, an immunoglobulin (Ig) panel can be performed. This panel measures the levels of different types of immunoglobulins (IgG, IgA, IgM, IgE) in the blood, which can help identify immune system abnormalities. Elevated IgE levels are commonly seen in patients with WAS.
