| Ped said he's 100 percent convinced ds has flu despite negative flu tests. Is that possible or is dr a quack? |
| Completely possible. |
| The test only tests for a few major strains, not all of them. |
Yes, is possible. In house test checks for A and B, not C strains |
| How did they test? Testing for viral presence is costly and slow. Normally one is tested for the presence of antibodies. Which means you do not ever test negative. You test positive or not positive. If you test not positive, your chances are 50-50. |
