Rule out illness: When infants/toddlers have bruises in unsuspecting areas, blood tests are done to rule out ITP (idiopathic thrombocytopenia purpura). This is an autoimmune disorder, self-limited and lower platelet counts occur with the bruises. It should be monitored since if the Platelets drop below 10,000 they often need admission to a hospital or treated as an outpatient. You should follow up on the tests.

Confirmation: The numbers you give are not very helpful but platelets of 90(thousand) are on the low side.What .7 neuts refers to is confusing. You repeat a test to see if the initial test was wrong, the levels change or to define the problem more clearly. Low platelets could be a technical glitch, a problem with production or excessive destruction.Further testing narrows your search.
