Researchers outline a new minimally invasive and inexpensive blood test that can identify cancer in patients with non-specific symptoms and whether these cancers have metastasised in the body.
Drug delivery, blood extraction, contrast agent injection – many procedures in modern medicine would be utterly impossible without needles. Despite the benefits, inserting pointy metal tubes into a patient also comes with several drawbacks. By downscaling the to micrometer-size, Japanese researchers open even more areas of application for needles, while bypassing some of the most important…
The Swiss-based CAMAG DBS Laboratory in collaboration with the Institute of Forensic Medicine in Bern, Switzerland, has developed a novel approach for the fully automated analysis of the direct alcohol marker phosphatidylethanol (PEth) in dried blood spots (DBS). The use of a DBS autosampler with an embedded hematocrit (HCT) scanner combined with an LC-MS system permits analysis of large…
Researchers have found that regular blood tests can help detect whether prostate cancer patients have resistance to drugs treating the condition. The findings were presented at the National Cancer Research Institute (NCRI) virtual Festival.
Treating diseases such as Alzheimer’s or Parkinson’s is a challenge because drugs have to be able to cross the blood–brain barrier. As a result, the doses administered must be high and only a small fraction reaches the brain, which can lead to significant systemic side effects.
Blood transfusions save lives, yet the precious fluid is in desperately short supply around the globe. But what if transfusions don’t always require blood? A new mathematical model of the body’s interacting physiological and biochemical processes – including blood vessel expansion, blood thickening and flow-rate changes in response to the transfusion of red blood cells – shows that…
Autoimmune hepatitis (AIH) is a chronic liver inflammation that is triggered by an immunological malfunction. In this case, the immune system falsely recognises the patient's own liver cells as "foreign to the body". The symptoms of this rare liver disease are unspecific, and the exact cause is not yet known. If left untreated, AIH can lead to abnormal scarring (fibrosis) of the liver,…
If the suspicion of Alzheimer's disease creeps up, those affected must prepare themselves for lengthy and complex procedures until the case is clear. A team from Empa and the Cantonal Hospital of St. Gallen is now in the process of developing a blood test that will enable a reliable diagnosis using atomic force microscopy (AFM).
By analysing secondary acute myeloid leukaemias, researchers at the Institute for Research in Biomedicine (IRB) Barcelona have detected mutations caused by platinum-based chemotherapies in cells that were healthy at the time of treatment. Treatment with chemotherapies influences the development of blood cells, favouring clonal hematopoiesis from cells with pre-existing mutations. The study has…
On World Sepsis Day, in vitro diagnostics company bioMérieux and the UK Sepsis Trust reveal the results of a survey conducted in Europe regarding knowledge and attitudes towards sepsis. The findings demonstrate the need to accelerate awareness and education of the general population about this life-threatening condition.
Researchers from the University of Oxford have announced the results of a study into thrombocytopenia (a condition with low platelet counts) and thromboembolic events (blood clots) following vaccination for Covid-19, some of the same events which have led to restricted use of the Oxford-AstraZeneca vaccine in a number of countries.
Researchers at Karolinska Institutet recently reported that magnetic resonance imaging (MRI) could reduce overdiagnoses and thereby improve prostate cancer screening. Now, the same research group has published a study in The Lancet Oncology, which shows that the addition of a novel blood test, the Stockholm3 test, can reduce the number of MRIs performed by a third while further preventing the…
Markers in our blood – ‘fingerprints’ of infection – could help identify individuals who have been infected by SARS-CoV-2, the coronavirus that causes Covid-19, several months after infection even if the individual had only mild symptoms or showed no symptoms at all, say Cambridge researchers. The team has received funding from the National Institute for Health Research to develop a test…
The Lausanne University Hospital (CHUV) and EPFL teamed up to develop a new test that’s sensitive enough to measure the amount of SARS-CoV-2 neutralizing antibodies present in the bloodstream. The scientists’ discovery, published in Science Translational Medicine, opens promising new avenues for tracking immunity acquired by infection or vaccination.
Final results from a study of a blood test that can detect more than 50 types of cancer have shown that it is accurate enough to be rolled out as a multi-cancer screening test among people at higher risk of the disease, including patients aged 50 years or older, without symptoms. In a paper published in the cancer journal Annals of Oncology, researchers report that the test accurately detected…
A simple blood test could help doctors spot deadly damage to the aorta, the body’s largest blood vessel, according to research funded by the British Heart Foundation (BHF) presented at the British Cardiovascular Society conference.
A team of Johns Hopkins researchers has developed a rapid blood test that could confirm a person has been vaccinated while they wait to board a plane or enter a sporting event.
Greiner Bio-One presents the Vacuette® Evoprotect Safety Blood Collection Set - the ideal choice for venous blood collection and short-term infusion of intervenous fluids.
MiniCollect® offers a gentle way to collect small blood samples for a wide range of analyses. The capillary blood sample is becoming increasingly popular as specimen material due to its simpler and less invasive sampling procedure. One of the advantages is the low blood volume. Small quantities are sufficient to enable a variety of parameters to be tested.
A large study from Denmark and Norway published by The BMJ sheds more light on the risk of rare blood clots in adults receiving their first dose of the Oxford-AstraZeneca Covid-19 vaccine. The findings show slightly increased rates of vein blood clots including clots in the veins of the brain, compared with expected rates in the general population. However, the researchers stress that the risk of…
The brand-new Vacuette® Evoprotect Safety Blood Collection Set is the next evolution of safety.
A team led by a clinical academic at University College London (UCL) has outlined the mechanism behind rare cases of blood clots and low platelets seen in patients who have had the Oxford/AstraZeneca vaccine. The new study, published in the New England Journal of Medicine, highlights the importance of rapidly spotting this new syndrome, known as vaccine-induced thrombosis and thrombocytopenia…
Researchers at the University of Oxford report that the risk of the rare blood clotting known as cerebral venous thrombosis (CVT) following Covid-19 infection is around 100 times greater than normal, several times higher than it is post-vaccination or following influenza. The study authors, led by Professor Paul Harrison and Dr Maxime Taquet from Oxford University’s Department of Psychiatry and…
Siemens Healthineers announced the company's Atellica VTLi Patient-Side Immunoassay Analyzer has obtained CE mark and is expected to be available later this spring. The Atellica VTLi analyzer provides lab standard, high-sensitivity cardiac troponin I (hs-cTnI) test results to clinicians in eight minutes using a patient's fingerstick blood sample. With this industry first technology, Siemens…
New research has shown that results of blood tests routinely performed by GPs everywhere contain a hidden fingerprint that can identify people silently developing potentially fatal liver cirrhosis. The researchers have developed an algorithm to detect this fingerprint that could be freely installed on any clinical computer, making this a low-cost way for GPs to carry out large scale screening…
