Hi mama! I'm not from Pasig kaya hindi ko masyadong familiar ang PCGH system, but a few of us did swab tests during pregnancy at iba't ibang hospitals, usually kailangan mag-schedule para ma-sure ang slot, especially ngayon. Best thing talaga is to call PCGH directly para malaman mo exactly kung kailangan ba scheduled or pwedeng walk-in, at para ask about the exact price kasi it varies. Pero generally may bayad talaga for swab tests, usually between 500-1500 pesos depending sa type, pero better to confirm with them directly para sure ka na! Congrats sa first baby, mama!
