CAFFEINE

The CAFFEINE test is a home sample collection service with laboratory analysis that measures circulating caffeine and its primary metabolites in blood to quantify recent caffeine exposure. Samples are analysed using validated chromatographic or mass‑spectrometry methods to provide an accurate serum/plasma caffeine concentration. This information helps identify excessive intake, potential caffeine toxicity, or low levels that may explain symptoms related to sleep, energy or cardiovascular effects.

This test is useful for adults experiencing sleep disturbances, unexplained palpitations, anxiety after caffeine consumption, athletes seeking performance optimisation, or patients whose medications may interact with caffeine metabolism. A trained phlebotomist collects the sample at home in Dubai, and results are provided with interpretation guidance; abnormal findings should be reviewed with a physician for personalised recommendations and follow-up.
