The GP sent me to the hospital for a lung x-ray and some labs. The results for d-dimer already got back to my GP (blood was drawn about 90 minutes ago) and she called to let me know that one was negative - it was to rule out an embolism, based on my current issues + coughing up a couple globs of blood two weeks ago. Also being tested: ESR, hemoglobin, "gluc"(ose?), Gamma-glutamyl transpeptidase, alanine aminotransferase, TSH, NT-proBNP (congestive heart failure), CRP, and "leukocytes and differential" under the category of "infectious mononucleosis". The GP also got to experience my blood pressure issues again ... took her 5 tries to get a reading doing it by hand, and she said it was very faint.
