Laboratory Studies

There is no biomarker that can be used to identify acute poisoning from white phosphorus. However, a basic trauma panel that includes the following should be obtained:

  • Complete blood cell count (CBC)

  • Basic metabolic panel

  • Prothrombin time (PT), activated partial thromboplastin time (aPTT), or both

  • Blood type and crossmatch

In addition, the following should be obtained:

  • Serum calcium, phosphorus, and magnesium levels
  • Urine phosphate levels
