Chest pain is a common symptom; 20% to 40% of the population will experience chest pain during their lifetime. There are many causes of chest pain, some of which are benign, while others are potentially life threatening. Importantly, in patients with chest pain caused by an acute coronary syndrome (ACS) or angina, there are effective treatments to improve symptoms and prolong life, emphasising the importance of early diagnosis in patients where chest pain may be of cardiac origin (Skinner et al, 2010). Chest pain is one of the most common reasons for emergency admission to hospital and is a heavy burden on health-care resources. A strategy to identify low-risk patients suitable for immediate discharge would have major benefits (Shah et al., 2015).

A review of the trust’s chest pain pathway, by a consultant acute care physician, was conducted following a need to increase patient discharge rates and reduce hospital admissions.
The introduction of high-sensitivity troponin I (hs-TnI) allowed clinical practitioners in the UK to implement a novel and radically different chest pain pathway. The new pathway uses an admission hs-TnI of <1.9ng/L to discharge patients with suspected acute coronary syndrome (ACS).
The percentage of chest pain patients admitted to the hospital declined from 60.9% to 38.4% and the mean length of stay reduced from 23 hours 2 minutes to 9 hours 36 minutes. (Ford, 2017)
What it means
The adoption of high-sensitivity Troponin I (hsTnI) has allowed RWT to relieve pressure on their emergency department by discharging patients with a hs-TnI level below 1.9ng/L, the limit of detection for the assay.[/mpc_icon_column]
Accurate test results are vitally important in diagnosis of chest pain and effective quality control is crucial to achieving this. The Randox Liquid Cardiac Control Level 1 features ultra-low levels of Troponin I, enabling it to challenge the sensitivity of analysers, ensuring confidence in vital clinical decisions.
Features & Benefits
Liquid ready-to-use – enables ultimate ease-of-use, saving time and money. Suitable for both clinical laboratories and point-of-care testing (POCT), where important clinical decisions are made.
100% human serum – ensures complete commutability whereby the control mimics a real human sample, reducing annoying shifts with a change in reagent batch.
Consolidation – comprising an impressive 8 cardiac markers, featuring ultra-low levels of Troponin I meaning a separate high-sensitivity control is not required.
Open vial stability of 20 days at 2°C – 8°C for all analytes – enables less wastage, saving money.
