My mom has had fever for the last 12 to 13 days along with severe headache. I consulted a physician who prescribed antibiotics and painkillers. We also did several tests including blood and urine, but nothing abnormal was found. However, after taking the medicines, her fever seems to be getting higher. The doctor is still unable to identify the reason for her fever. What could be the possible cause?

If fever persists and all reports are inconclusive, consider testing for viral infections, autoimmune conditions or do imaging. A detailed consult is needed.

I have had two miscarriages, one at 14 weeks and another at 12 weeks. My doctor advised me to do some tests, including APLAS, ELISA, EIA, IgM, and IgG. I have received my reports, but I am not sure how to read them. Please help me understand whether my reports are negative or positive.
