If you get tested to soon or too late your antibody level will not be high enough to trigger a positive result. If your family got them at varied times after infection, or if you got more than one test, it would be very unlikely you hadn't gotten a positive result. Conventional wisdom is that it peaks ~3 weeks after infection, and is highest for 1-2 weeks around that time. In practice everyone reacts differently and it can be hard to predict. I was infected in March and I'm still testing positive every 1-2 weeks. That's because I had a fairly rough go round, and developed a very heavy immune response. Asymptomatic[1] people may mount a very limited response and never test positive for antigens at all. > Since then, I've had a persistent "throat-clearing" thing. Lots of "harUMPHf." My sense of taste never fully recovered, either (that was the weirdest part of it. I've never had that happen before). It took me an inhaler and 4+ months to clear out my lungs. Constantly coughing up thick sludge. That inhaler was a godsend during the worst part of it- helped me move stuff around when I needed air most. I still have breathing issues (damage to the blood vessels), but I can fill my lungs easily now. [1]: NB that due to the way lung problems work, "asymptomatic" cases can still inflict a lot of damage. Since your oxygen demands and supplies are constantly changing -due to exertion, air quality, altitude etc- your body is used to quietly adjusting your heart rate and breathing rate up without you noticing. Your lungs can go through some serious losses of efficiency and put a lot of strain on your heart before you notice. This goes double for people with high anaerobic tolerance; if you run a few times a week you will just ignore co2 buildup to a much higher level than a couch potato.
