Hello ,

Normal WBC is 4 to 10 so yes 18.5 is very high ...

Any fever ?

Infection most common cause ...

Blood problems / marrow problems up to leukemia can be potential concern however ...

Expert:  Anthony Bray, MD replied 1 month ago.

Seeking infection is first step with your results

Sed rate / C-reactive protein / urinalysis / urine culture/ chest xray or CT / sinus CT/ blood cultures / echocardiogram /

Pneumonia or kidney infection or endocarditis can cause huge elevations of WBC ( neutrophil highest )

Expert:  Anthony Bray, MD replied 1 month ago.

Have you had fever ? Chills ? Night sweats ?

Any symptoms of concern?

Do you know what type cells were high ? Neutrophils, monocytes , lymphocytes ,other ?

Attention first would typically be as I mentioned to look for evidence of infection

Expert:  Anthony Bray, MD replied 1 month ago.

If there is not infection as explanation for very high WBC then investigation may turn to look for blood pre-malignant or malignant conditions

SPEP = serum protein electrophoresis is used

Blood smear review by pathologist may be done

Bone marrow biopsy is done if needed ...( not first done of course on that ...Other reasons sought before resorting to that measure )
