Urine analysis might detect drugs taken in the past 2–3 days; hair analysis can sometimes detect use as far as 90 days, although certain cosmetic treatments (e.g. dyeing hair) can interfere ...

Radiation induces hair loss through damage to hair follicle stem cell progenitors and alteration of keratin expression. [72] [73] Radiation therapy has been associated with increased mucin production in hair follicles. [74] Studies have suggested electromagnetic radiation as a therapeutic growth stimulant in alopecia.

Currently, most entities that use hair testing have prescribed consequences for individuals removing hair to avoid a hair drug test. Most drugs are analysed in hair samples not as the original psychoactive molecules, but rather as their metabolytes. For example, ethanol is determined as ethyl glucuronide, while cocaine use is confirmed using ...
Traditional techniques typically take between 12 and 48 hours, [6] although it can take up to five days. [28] In contrast, rapid testing using molecular diagnostics is defined as "being feasible within an 8-h(our) working shift". [6] Progress has been slow due to a range of reasons including cost and regulation. [40]
Metformin itself isn’t thought to cause hair loss, but type 2 diabetes and PCOS (polycystic ovary syndrome) — the conditions it’s prescribed to treat — can cause hair loss.
About 60% of the metronidazole is metabolized by oxidation to the main metabolite hydroxymetronidazole and a carboxylic acid derivative, and by glucuronidation. The metabolites show antibiotic and antiprotozoal activity in vitro. [61] Metronidazole and its metabolites are mainly excreted via the kidneys (77%) and to a lesser extent via the ...
