I'm 20 and dealing with a connective tissue disorder. I'm really worried because I've been seeing rusty-colored blood in the morning and coughing up a little blood. The pulmonologist recommended a chest CT scan, and they mentioned that my DNS is normal and "cancapanca" is normal too. But my aPTT is at 30.0 seconds and prothrombin with INR is at 16.1 seconds, and my INR range is 1.36 seconds. My ANA test came back positive. I'm confused about what all these results mean and what could be causing these symptoms. Could you help explain this?

Probable diagnosis is upper respiratory tract infection.Patient is advised tab augmentin 625mg orally,thrice dailly for 5 days,tab levocetrizine 10 mg for 5 days and syrup salbutoml 10 ml thrice dailly for 5 days.
