toxicology report

[tsmith2981]

I am trying to understand a toxicolgy report of blood samples taken and it seems conflicting to me.  The following are the results:

1. ethyl alcohol  - none detected
2. benzodiazepines cross reactivew  - positive
3. alprazolam - 100 nanog/ml - (prescribed drug taken as directed)
4. cocaine cross-reactives  - positive
5. cocaine - none detected
6. cocaethylene - none detected
7. benzoylecgonine - 860 nanog/ml
8. diphenhydramine -  -35 nanog/ml
9. diphenhydramine metabolite - positive

What is the definition of #7 and what does the 860 nanog/ml mean?  This information is for self education only and not to be used for any other purpose.

Thank you

Thank you for your answer.  But, is the reading of  860ng/ml a high reading?  Is it a cumulative reading?  I am not sure what to make of it.

Thanks

The term “nanog/ml” is a measurement of concentration (amount) of a substance in a given volume of liquid (in this case blood). It stands for nanograms (a unit of measure for weight) per milliliter (a unit of measure for volume). Benzoylecgonine is a metabolite (the body changes substances put into it into other substances that can be measured) of the narcotic cocaine and can be measured by urine or hair samples and allows someone to tell long-term if an individual has used this substance. The number 860ng/mL means that is the concentration of benzoylecgonine found upon testing of the sample.

does that answer mean you cannot answer this question?
