Your d-dimer seems marginally elevated.. we need to correlate your d dimer with your symptoms/in relation to the day of test and along with other inflammatory markers suck as LDH/
ferritin/IL6/hsCRP/ESR
You can let me know about any increasing breathlessness or swelling in the legs
Next Steps
Inform me the said investigation..depending upon your history we can plan if repeat d-dimer is needed or we need to start some blood thinners
