Rontgen Toraks Normal Tidak Dapat Menyingkirkan COVID-19

Oleh :

dr. Nurul Falah

Hasil rontgen toraks yang normal tidak dapat menyingkirkan kemungkinan diagnosis COVID-19. Akurasi rontgen toraks untuk mendiagnosis COVID-19 dilaporkan lebih rendah daripada CT scan toraks. Namun, rontgen toraks memiliki harga yang lebih terjangkau dan hampir selalu tersedia di seluruh rumah sakit, sehingga sering dilakukan sebagai pemeriksaan awal.[1,2]

Baku emas diagnosis COVID-19 adalah pemeriksaan real-time reverse-transcriptase polymerase chain reaction (RT-PCR) dari sputum dan swab tenggorok, yang kemudian dilanjutkan dengan genome sequencing untuk mendeteksi ribonucleic acid (RNA) virus SARS-CoV-2. Namun, RT-PCR membutuhkan biaya relatif mahal dan memiliki distribusi terbatas di area terpencil, sehingga pencitraan sering menjadi alternatif.[3-5]
