LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.

LP411415-5   4-Fluorofentanyl
The compounds known as novel synthetic opioids (NSOs) have been emerging as drugs of abuse, given that many share pharmacological properties with common opioid agonists, yet they are difficult to detect and control. Since the early 2010s clandestine manufacturing of both novel fentanyl derivatives as well as other synthetic opioids has increased, with the list growing to upwards of more than 30 unique compounds. The list includes fentanyl analogs such as acetylfentanyl, butyrfentanyl, 4-methoxybutyrylfentanyl, 4-methylphenethylacetylfentanyl, furanylfentanyl, carfentanil (and its major metabolite norcarfentanil), ocfentanil, acrylfentanyl, 3-methylfentanyl and 4-fluorobutyrylfentanyl. Also, in the same category are non-fentanyl derived chemicals having opioid agonist activity such as AH-7921 and U47700(benzoamides) and MT-45 (a piperazine). The pharmacologic receptor profile of some predict that they would be highly addictive and in some cases much more potent (for example, 3-Methylfentanyl is about 1000 times and carfentanil may be 10,000 times more potent than morphine). The fact that they are often cut into heroin preparations or sold as counterfeit pain killers with users unaware of their content makes them particularly prone to overdose. The DEA has reported that the fentanyl crisis in the United States in the late 2010s has been largely fueled by NSOs PMID: 30634521. Source: Regenstrief LOINC
