Abstract
|
|
|
|
D-dimer level, along with a clinical probability tool that uses the Wells score, is commonly used to exclude deep vein thrombosis (DVT). Age-adjusted D-dimer values are routinely used in clinical practice to increase the negative predictive value and avoid unnecessary Doppler ultrasound imaging. We describe a patient with a low pre-test probability of DVT upon admission and a negative D-dimer level based on age-adjusted values who was later diagnosed with DVT. Our experiences with this case highlight that the geriatric population is unique and, at times, frail.
