Preeclampsia is a well known condition, affecting around 6% of all pregnancies. It is typically characterised by proteinuria and high blood pressure, but some with the condition have no symptoms and progression can be unpredictable. It can pose significant risks to both the mother and the baby if left untreated, with many currently available tests requiring blood draws and lengthy lab analysis.
Lumella is a new point-of-care risk assessment tool, with digital results in 10 minutes using only a single drop of blood. Multiple hospitals are scheduled to trial Lumella in the UK this year.
Introducing Lumella
Lumella represents a significant development in PE testing, offering a non-invasive and accurate method for preeclampsia screening. Lumella uses the novel biomarker, GlyFN, demonstrating excellent outcomes when compared with other available biomarker tests, including PlGF, with a specificity of 92.8% and sensitivity of 98.5% 1. GlyFN levels are significantly elevated even as early as the first trimester in patients with preeclampsia.
How Lumella Works
The Lumella test can be taken and analysed entirely by bedside. Using a handheld digital reader included in the test kit, the simple 4-step process generates a ‘normal’ ‘positive’ or ‘high positive’ result in just 10 minutes. A high positive result indicates there is a high risk of delivery within 14 days, as well as other severe complications such as HELPP syndrome.
The Benefits of Lumella
High accuracy when compared to other available tests
Quick and simple 4-step testing procedure
No specialised lab equipment, centrifugation, or cold storage required
Cost and time effective - reduces unnecessary admissions
Minimally invasive - only a single drop of blood required
All necessary equipment - such as lancet, swab, reader, and cartridges - are included in the kit
Supported by an ever-growing library of evidence
