If your testosterone levels—or those of someone you love—are low‚ you may start to notice that low testosterone or “low T” is not only affecting your sex drive‚ but also your feelings of self-confidence and sleep patterns. Men with hypogonadism often have problems with sadness and memory. Low levels of testosterone can also lead to loss of muscle mass in men‚ who may also experience fewer erections and problems with fertility. Taking a testosterone supplement like Deseret Biologicals’ Testosterone can help resolve some‚ if not all‚ of these side effects.
This application note describes the extraction of cocaine and major metabolites from whole blood, prior to GC/MS analysis. This protocol also allows the simultaneous extraction of various other drugs of abuse classes: amphetamines, barbiturates, benzodiazepines and opiates.
ISOLUTE® SLE+ columns with 1 mL sample capacity are used to extract whole blood samples following a straightforward sample dilution. No protein precipitation or other pre-treatment is required prior to sample loading. The sample preparation procedure delivers clean extracts, good recoveries and RSD values and LLOQs from 20 ng/mL (analyte dependant).
