Alprazolam may be quantified in blood or plasma to confirm a diagnosis of poisoning in hospitalized patients, provide evidence in an impaired driving arrest, or to assist in a medicolegal death investigation. Blood or plasma alprazolam concentrations are usually in a range of 10–100 μg/L in persons receiving the drug therapeutically, 100–300 μg/L in those arrested for impaired driving, and 300–2000 μg/L in victims of acute overdosage. Most commercial immunoassays for the benzodiazepine class of drugs cross-react with alprazolam, but confirmation and quantitation is usually performed using chromatographic techniques.   
Hello. I’m curious what you mean that you still suffer from the clot you had years ago. It didn’t dissolve with the Nattokinase and Serrapeptace? Do you suffer from the medicine they had you on? This concerns me because I’m trying to decide if I should take the xarelto my doctor prescribed for the small clot I got from a vein surgery I recently had or if I should stay on the Nattokinase and Serrapeptace I started two days ago. I felt nauseous and scared this morning because my dr told me I’ll be fine as long as I take xarelto. I also might have taken too much. 3times yesterday and also Vit. E, fish oil and aspirin. I might have overdone it. Your opinion would be appreciated.
My dad takes metformin for his diabetes (ok, so his entire side of the family takes it for diabetes— PCOS and diabetes run through out my family history) and he suggested that I start with 1 a day for 2 weeks and then work up to my 2 a day suggested dose after that. I have found that waiting for my meal to settle a little while (usually about 15-20 minutes really helped me to avoid a lot of discomfort. I already have bathroom “issues” (I tend to go A LOT; a very regulated 30 minutes after I put anything in my mouth) so by waiting it just kind of wrapped into my normal habit and seemed a lot less intense.
