The laboratory data showed, in addition to the typical SCD findings, other abnormalities such as reactive thrombocytosis (399,500 ± 209,100/μL), elevated CRP (13.8 ± 9.7 mg/dL), and increased alkaline phosphatase (157.5 ± 88.5 IU/L), which may support the diagnosis of osteomyelitis (Table 2). Here, CRP is linked to osteomyelitis.
