JamesA fibrinogen blood test measures fibrinogen, also called coagulation factor I, in a blood sample. Fibrinogen is made mainly by the liver and is converted into fibrin during clot formation. The test can be used when clinicians investigate unexplained bleeding, abnormal clotting tests, disseminated intravascular coagulation (DIC), major haemorrhage or selected pregnancy-related problems. High or … Read more
Quality control vs quality assurance is the difference between checking whether day-to-day testing is performing as expected and managing the wider system that makes laboratory results reliable. Quality control (QC) includes activities such as running control materials, reviewing shifts and trends and deciding whether an analytical run is acceptable. Quality assurance (QA) is broader: it … Read more
NHS vs Private Laboratory Work NHS vs Private Laboratory Work: What’s the Difference for Biomedical Scientists? For a biomedical scientist, the biggest difference between NHS vs private laboratory work is not the science itself but the employment structure around it. NHS laboratories usually operate within nationally defined Agenda for Change pay bands, public-sector pension and … Read more
UK vs Australian Biomedical Scientist UK vs Australian Biomedical Scientist: Qualifications, Registration and Career Differences A UK vs Australian biomedical scientist comparison starts with terminology and regulation. In the UK, Biomedical Scientist is a legally protected title regulated by the HCPC, and the common NHS career structure uses Agenda for Change bands. In Australia, comparable … Read more
Neutrophils vs Monocytes Neutrophils vs Monocytes: What’s the Difference and What Do Your Levels Mean? Neutrophils vs monocytes are two types of white blood cell with overlapping roles in innate immune defence but different behaviour. Neutrophils are rapid, short-lived responders that are especially important in early responses to many infections and tissue injury. Monocytes circulate … Read more
Haemoglobin vs Haematocrit Haemoglobin vs Haematocrit: What’s the Difference and What Do Your Results Mean? Haemoglobin vs haematocrit compares two closely related measurements in a full blood count, but they are not the same result. Haemoglobin (Hb) measures the concentration of the oxygen-carrying protein haemoglobin in blood, usually reported in grams per litre (g/L). Haematocrit … Read more
T Cells vs B Cells T Cells vs B Cells: What’s the Difference and How Are They Tested? T cells vs B cells is a comparison between the two major lymphocyte arms of adaptive immunity. Both arise from haematopoietic stem cells in the bone marrow, but T cells mature primarily in the thymus and coordinate … Read more
Basophils vs Eosinophils Basophils vs Eosinophils: What’s the Difference and What Do High Levels Mean? Basophils vs eosinophils compares two relatively uncommon granulocyte types found in the white-cell differential. Both contain cytoplasmic granules and can participate in inflammatory and allergic responses, but their biology and the conditions associated with raised counts differ. Eosinophils are particularly … Read more
Creatinine vs eGFR Creatinine vs eGFR: What’s the Difference and What Do Your Results Mean? Creatinine vs eGFR compares a measured blood marker with a calculated estimate of kidney filtration. Serum creatinine is a waste product generated mainly from normal muscle creatine metabolism and measured directly in a blood sample. Estimated glomerular filtration rate (eGFR) … Read more
Acute vs Chronic Inflammation Acute vs Chronic Inflammation: What’s the Difference and How Are They Tested? Acute vs chronic inflammation describes two different time-courses of the body’s inflammatory response. Acute inflammation starts rapidly in response to injury, infection or tissue damage and is designed to contain the problem and begin repair. Chronic inflammation persists for … Read more
