Uy, mama, para sa PT (prothrombin time) test results, importante talaga na tanungin mo directly ang doctor mo about the accuracy, ha? Lalo na kung ito ay para sa health concern mo or ng baby. Kung worried ka about test results, better to ask your healthcare provider kung saan ginawa and kung trustworthy ang lab, alam nila best! A few of us moms always verify with our OB or pedia kung may doubts kami sa results.
