1H-NMR spectroscopic molecular markers are provided for identifying medical risk signatures such as SARS-CoV-2 infection, acute inflammation, or a cardiovascular risk condition. The markers use a combination of NMR intensity signals, including a Glyc signal from at least one N-acetyl (-NCOCH3) glycoprotein and an SPC signal from a choline head group (+N-(CH3)3) of a supramolecular phospholipids cluster (SPC) present in HDL and LDL lipoprotein subfractions. The Glyc signal is in a chemical shift region from ẟ = 2.00 ppm to ẟ = 2.20 ppm, and includes signals GlycA (2.00 ppm to 2.09 ppm) and GlycB (2.09 ppm to 2.2 ppm). The SPC signal is in a chemical shift region from ẟ = 3.20 ppm to ẟ = 3.30 ppm, and includes signals SPC1 (3.2 ppm to 3.235) ppm, SPC2 (3.235 ppm to 3.26 ppm), and SPC3 (3.26 ppm to 3.3 ppm). A system for identifying the markers is also provided.
