About

Shannon Haymond is a clinical mass spectrometrist whose work bridges analytical chemistry and patient care, with a focus on developing robust, high-throughput methods for therapeutic drug monitoring and renal function assessment. Her most cited paper, "Determination of iohexol in human serum by a semi-automated liquid chromatography tandem mass spectrometry method" (2015, 18 citations), exemplifies her contribution to precision medicine: she pioneered a semi-automated LC-MS/MS approach for measuring iohexol, a non-radioactive contrast agent used as a gold-standard glomerular filtration rate (GFR) marker. This work directly addresses the need for accurate, reproducible kidney function testing, reducing manual error and enabling clinical labs to adopt iohexol clearance as a routine alternative to creatinine-based estimates. Beyond this study, Haymond’s research portfolio includes innovations in steroid hormone analysis and immunosuppressant monitoring, often leveraging automation to increase throughput without sacrificing specificity. Her impact is felt in both the laboratory and the clinic, as her methods have been adopted by major medical centers to improve diagnostic accuracy for patients with chronic kidney disease and transplant recipients. A recognized leader in clinical mass spectrometry, she continues to shape how metabolomics and proteomics translate into actionable diagnostic tools.
