The complete blood count can be normal. However, the WBC count is elevated in as many as 60% of patients who have torsion.

Elevation in acute-phase proteins (ie, C-reactive protein) has been postulated as a diagnostic aid in differentiating inflammatory causes of acute scrotal pain (eg, epididymitis) from noninflammatory causes (eg, testicular torsion). [29] However, sample sizes in these studies have been too small to support using CRP as a diagnostic adjunct to definitively rule out testicular torsion.
