That 99% accuracy feels solid, but with rare things? Numbers play tricks. My little one had a scare last year—test said positive, but the doctor said to wait. He explained that if only 1 in 1000 people have it, even a "99% right" test will light up mostly for the healthy ones. We held our breath for the second test. It came back clean, thank God. Now I see the numbers, but I also see my son's face that whole week. The maths isn't what you hold onto.
