Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
The sex hormone binding globulin (SHBG) test may be used to help evaluate men for low testosterone and women for excess testosterone production. It may be ordered in conjunction with other tests to evaluate the status of a person's sex hormones.SHBG is a protein that binds tightly to the hormones testosterone, dihydrotestosterone (DHT), and estradiol (an estrogen). In this bound state, SHBG transports these hormones in the blood as biologically inactive forms.HBG is ordered primarily when the total testosterone results do not seem to be consistent with clinical signs and symptoms, such as infertility, decreased sex drive, and erectile dysfunction in men or infertility, irregular menstrual periods, and excess facial and body hair in women.
The results from EMG and nerve conduction studies are used along with your medical history, symptoms, physical and neurological exams, and the results of other tests to help your doctor find out what the problem is or see how a disease is changing.he speed of the response is called the conduction velocity. The same nerves on the other side of the body may be studied for comparison. When the test is done, the electrodes are removed. Nerve conduction studies are done before an EMG if both tests are being done.
