What is bone scintigraphy? Bone scintigraphy is a subtype of scintigraphy. Bones and their metabolism can be assessed very well with it. For this purpose, a radioactively labeled substance (radionuclide) is injected into the patient via a vein. The higher the local metabolic activity, the more it is deposited in the bone. The radiation emitted … Bone Scintigraphy: Definition, Reasons, Procedure
What normal values and reference range mean In order to detect diseases or monitor their progress, the physician can have measured values determined in the blood or other body fluids or in tissue samples in the laboratory. As a guide as to which values could be conspicuous, the laboratory gives normal values or reference ranges. … Normal values and reference range
How is THC detected? THC and its degradation products are detected with the help of special drug tests. On the one hand, these can be easy-to-use THC rapid tests – for example THC test strips – which give an indication of the consumption of cannabis. If the measured amount is above the so-called cut-off, the … THC Detectability in Blood, Hair, and Urine
What is a rapid drug test?
