What is a common laboratory result expected in clients infected with helminths?

Clients infected with helminths typically show an elevated white blood cell count, particularly an increased level of eosinophils. This elevation is part of the body's immune response to the presence of the parasitic worms. Eosinophils play a significant role in combating parasitic infections, as they are involved in inflammatory responses and help in the destruction of parasites.

The immune system detects the helminth infection and activates various components of the immune response, leading to an increase in eosinophils as well as a general elevation in white blood cell counts. This response can often be seen in laboratory tests, providing a helpful diagnostic indicator for healthcare providers when they suspect a helminth infection.

The other options do not typically correlate with helminth infections as a common laboratory finding. For instance, decreased glucose levels, high platelet counts, and increased potassium levels do not reflect the typical immunological response associated with helminthiasis.
