The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +
P(you don't have the disease)*P(the test shows positive when testing someone without the disease).
The second category is particularly important if the disease is rare but the probability of a type II error is large.
The knowledge of probability impacts one's understanding of drug testing or tests for a particular disease because the test parameter could come out either as true or false, making the probability to be 1/2 for either scenario or status.
It is called empirical or experimental probability.

No. Probability values always have to be positive.
Hashimoto's thyroiditis is an autoimmne disease that affects the thyroid gland. A positive ANA means that a person makes anti nuclear antibodies. The person makes antibodies against the debris from the natural breakdown of the nucleus of dead cells. 10 million Americans have a positive ANA, many have no disease at all. The older you are, the more likely you will have a positive ANA. In disease, what matters more than just testing positive is the immunfluorescent pattern, with each pattern indicating a different autoimmune disease.
The probability that a child has whooping cough and receives a positive test result depends on the test's sensitivity (true positive rate) and the prevalence of whooping cough in the population. If the test is highly sensitive, the likelihood of a positive result among those who actually have the disease is greater. Additionally, considering the overall prevalence of whooping cough will impact this probability. A precise answer requires specific values for sensitivity, specificity, and prevalence.
