From MAY 1st 2020 VirQ SARS-CoV-2 Fast One-Step PCR Test for the Detection of COVID-19 has been CE certified. Unlike most assays on the market, it is able to exclude false negative results caused by lack of cell material taken during sample collection. This multiplex-PCR with 3 colour detection is compatible with most common thermalcyclers. Click here for more information

MC Diagnostics are delighted to announce that our Quality Management System has been certified to ISO 13485:2016 by the leading UK Based EU Medical Body, BSI. What is ISO 13485:2016?

By obtaining this quality standard accreditation, this demonstrates MC Diagnostics true understanding of the requirements and highlights our commitment to conduct high-level quality control, product traceability, risk-management and the importance of meeting customer and regulatory requirements. Overall, giving our customers peace of mind that our products are designed, manufactured and delivered to a high-standard but also, that we are in ful

Haemovigilance is an important aspect of transfusion science concerning the minimization of adverse effects and adverse events. One of the more serious complications following a blood transfusion is a haemolytic transfusion reaction, where donor blood contains antibodies incompatible with patient blood. The adverse event occurs when red blood cells given during the transfusion are destroyed by the recipient’s immune system.

Coeliac disease is a T-cell-mediated chronic autoimmune disease which effects the absorption of nutrients in the small intestine due to surface inflammation. The symptoms are caused by disease-specific antibodies against endomysium or tissue transglutaminase, which inflict damage to the lining of the intestine upon ingestion of gluten. Commonly reported symptoms include stomach pain and cramping, nausea, ongoing fatigue, constipation, diarrhoea, weight loss, mouth ulcers and bloating. Around 1 in 100 people has coeliac disease although this can be easily misdiagnosed for other GI problems. Early diagnosis is critical, as the intake of gluten can have destructive effects on the small intestine causing malabsorption, malnutrition, lactose intolerance which can cause health complications including osteoporosis, iron deficiency anemia, vitamin B12 deficiency and bowel cancer. Coeliac susceptibility is associated with the DQA1*05:01- DQB1*02:01 (DQ2) and DQA1*03-DQB1*03:02 (DQ8) haplotype and is dominantly inherited. Additionally, DR3, DR7 and DR11 alleles can be used as genetic markers. Of patients with coeliac disease, 99.6% of those will carry DQ8 or DQ2 [1]. HLA-DQ genotyping can be useful in accompanying a clinical disease diagnosis and to evaluate the risk of disease in relatives of a patient. To effectively treat coeliac disease a strict gluten-free diet must be followed, helping the intestines heal - which should lead to complete resolution of symptoms and decrease the risk of complications from long term malabsorption.

Polymerase chain reaction (PCR) is a highly sensitive technique to amplify a single copy of DNA into millions to billions of copies of a targeted sequence. Whilst its sensitivity is advantageous it can also create a number of issues if the correct contamination control is not followed. During PCR, even the smallest amount of contaminating DNA can be amplified resulting in the wrong template amplification and causing false positive or ambiguous results. Contamination can arise from work surfaces, equipment or reagents which have been exposed to PCR products. To minimize the risk of contamination there are several preventative methods and aseptic techniques which must be carefully performed.

Bechterew’s disease or Ankylosing Spondylitis is a chronic autoimmune disease effecting sacroiliac joints, spine, and peripheral arthritis. The incidence of disease generally occurs during teenage years and is three times more prevalent in males than females (3:1 ratio) (1). Common symptoms of Ankylosing Spondylitis include back pain and joint swelling, stiffness and extreme fatigue. The HLA-B*27 protein is a variant of the human leukocyte antigen-B (HLA-B) and has a strong association with this autoimmune disease and is therefore, used as part of the diagnostic procedure (2, 3). A positive HLA-B*27 result is associated with a very high disease risk. In suspected cases of Ankylosing Spondylitis, a HLA-B*27 diagnosis provides an important contribution to the therapy of the patient. Around 3% to 6% of the people carrying the HLA-B*27 gene develop Anklylosing Spondylitis and more than 90% of all patients with a seronegative arthritis have this gene. From April 2018 our new HISTO TYPE B*27 realtime PCR kit for fast and easy detection of HLA-B*27 is available. The HISTO TYPE B*27 Q kit covers all common HLA-B*27 sub types. Moreover, the kit differentiates between the disease associated alleles and the sub types HLA-B*27:06 or HLAB*27:09, which are not associated with Ankylosing spondylitis (4). An easily implementable test compatible with most common realtime cyclers.Visit our technical page for further information on how this test is applied. 1.
