    Syringe touch spray tandem mass spectrometry distinguished glioma from nontumor brain tissue and classified tumors by molecular subtype and grade in approximately 3 minutes.

  • 2

    The study analyzed 86 human brain specimens, including 78 glioma samples and 8 nontumor samples, using 24,492 metabolite ratios.

  • 3

    The N-acetylaspartate-to-carnitine ratio distinguished glioma from nontumor tissue with 97% sensitivity, 100% specificity, and 98% accuracy against clinical diagnoses.

  • 4

    Ratios involving 2-hydroxyglutarate separated IDH-mutant from IDH-wild-type samples and distinguished some glioma grades in the study cohort.

  • 5

    In mixed tumor and normal tissue, some samples with substantial tumor content fell below the tumor-core cutoff, potentially limiting detection at heterogeneous margins.
