inPractice® - Diagnosis

Diagnosis of PCP with microscopic examination of bronchoalveolar lavage using silver methenamine stain is considered the gold-standard technique (Figure 2)^{[Kovacs 2001]}
Polymerase chain reaction–based methods performed on lower respiratory tract specimens and in noninvasive oral washes, and measurement of plasma S-adenosylmethionine, are also available^{[Alvarez-Martínez 2006; Larsen 2004; Chawla 2011; Oren 2011]}
PCP may be diagnosed clinically in resource-limited settings
