In the case presented, I think that getting a D-dimer test
would be the next best step.
However, despite the higher prevalence and incidence of elevated D-Dimer in cancer patients, it was observed by Ten et al, (21) that the NPV of D-Dimer test
in cancer patients was as high as non-cancer patients in their cohort of 1 739 patients (217 had cancer).
It was reported in a systematic review that outpatients with a low pretest probability and a negative D-dimer test
had a three-month incidence of DVT of 0.
Diagnosing DVT Your GP will advise you to have a specialised blood test called a D-dimer test
which detects pieces of blood clot that are loose in your bloodstream.
If the PERC test is positive, then low-risk patients should undergo a highly sensitive D-dimer test
In this study, D-dimer test
has been considered for the diagnosis of ICF, because it is presently regarded to be more specific for fibrin degradation products, while the formation of FDP, X, Y, D, and E fragments, may be either fibrinogen or fibrin derived following the plasmin digestion.
The safe and effective management of suspected PE, utilising a diagnostic algorithm that combines a validated clinical decision rule, the D-dimer test
and CTPA  has been documented in various studies in the past decade.
The diagnosis of PE was ruled out if D-dimer test
was normal in patients with Wells score ≤4 or revised Geneva score ≤3.
Its next test is a D-dimer test
for deep vein thrombosis, development of which is underway, he added.
A positive D-dimer test
is commonly followed by a computed tomography (CT) scan of the chest or a ventilation/perfusion scan to establish a PE or DVT diagnosis.
5% were offering a qualitative D-dimer test
samples were drawn and subjected to latex agglutination test.
