Blood Test. Urine test you speak of does not have a better detection rate. And, this urine test you speak of is not even in Phase I of testing. Meaning, it won't be ready to be filed for FDA for another 5 years.
Also that urine test marker LRG does not even have an ELIZA test - so will need formulation of an ELIZA test that works reliably. And then the cassette form if possible, before it can compete with APPYScore ELIZA test and upcoming cassette (15 minute) version.
Also the results of the LRG are very close to the APPY marker (S100-A8):

Another of the candidate biomarkers identified by the researchers, S100-A8, is currently being investigated by AspenBio Pharma as a blood-based appendicitis biomarker.

RESULTS: Test performance of 57 identified candidate markers was studied in 67 patients, with median age of 11 years, 37% of whom had appendicitis. Several exhibited favorable diagnostic performance, including calgranulin A (S100-A8), alpha-1-acid glycoprotein 1 (orosomucoid), and leucine-rich alpha-2-glycoprotein (LRG), with the receiver operating characteristic area under the curve and values of 0.84 (95% confidence interval [CI] 0.72 to 0.95), 0.84 (95% CI 0.72 to 0.95), and 0.97 (95% CI 0.93 to 1.0), respectively.
