💊 Did you know that certain medications, vitamins and dietary supplements can influence laboratory test results?
Blood tests provide important information about the body's biochemical, hormonal and metabolic activity. However, the values measured in a sample may sometimes be affected by substances taken before blood collection.
How can medications and supplements affect laboratory results?
➤ Prescription and over-the-counter medications may influence certain biochemical, hormonal or other laboratory parameters.
➤ Vitamins and mineral supplements may affect the measured levels of specific nutrients and related markers.
➤ Herbal supplements and other products may influence certain physiological processes or laboratory measurements.
➤ Biotin (Vitamin B7), commonly found in supplements for hair, skin and nails, may interfere with certain laboratory testing methods, potentially producing falsely high or falsely low results.
🔍 Why is this information important?
Not every medication or supplement affects every blood test. The impact depends on the substance, dosage, timing and laboratory method used.
In some cases, specific preparation instructions may be necessary to support accurate and reliable measurements.
💡 Before undergoing laboratory testing, it is important to inform the laboratory and your healthcare professional about any medications, vitamins or supplements you are taking.
Prescribed medication should never be discontinued without medical guidance.
🔬 At MediCheck Clinical Laboratory, we recognise that reliable results begin with proper preparation and careful sample collection. Attention to pre-analytical factors supports accurate laboratory assessment and consistent testing procedures.
