New Acusera Quality Controls

Quality Control is our passion; we believe in producing high quality material that can help streamline procedures, whilst saving time and money for laboratories of all sizes and budgets. With an extensive product offering, comprising third party quality controls & calibrators, interlaboratory data management, external quality assessment, you can count on reliable results and peace in mind for your data quality managment.

New third-party Acusera controls:

New HIL/Serum Indices Quality Control

Identify pre-analytical errors in haemolytic, icteric and lipemic samples with the new Acusera Serum Indices Control. 

The release of the new version of ISO 15189 (2022), introduces increased focus on risk stratification and mitigation for patients and laboratory stakeholders and more emphasis on quality control to improve accuracy and validity of results.
Interference caused by haemolysis, icterus and lipemia is responsible for many rejected results and incorrect diagnosis. It is therefore important to accurately capture the presence of interfering substances in samples before quantitative analysis is carried out.
HIL (Haemolysis, Icterus, Lipemia) interference can have detrimental effects on the determination of concentration of many analytes. It is therefore crucial to determine levels of HIL interference to improve laboratory efficiency and to reduce the frequency of erroneous results. HIL interference leads to poor test turnaround times and additional expenses as sample collection and analysis must be repeated in cases of haemolysis, icterus or lipemia in samples. More serious consequences
of poor HIL detection may be delayed or incorrect diagnosis of patient samples, leading to late or inappropriate treatment.

Anti-Müllerian Hormone (AMH)

New Anti-Müllerian Hormone (AMH) Quality Control

The Randox Acusera AMH control is designed to use as a third-party control for the quantitative determination of Anti-Müllerian Hormone (AMH). An AMH test is often used to check a woman’s ability to produce eggs that can be fertilized for pregnancy. The number declines as a woman gets older. AMH levels help show how many potential egg cells a woman has left. Thus, helping women to make informed decisions about their health.
