Monocyte normal value, according to a lab that did that type of test on me (lab values vary) 1.7-9.3 percent, so yours would be low than at 1.1. Digoxin toxicity with normal digoxin and serum potassium levels: beware of magnesium, the hidden malefactor. Raja Rao MP(1), Panduranga P, Sulaiman K, Al-Jufaili M. Author information: (1)Department of Emergency Medicine, Royal Hospital, Muscat, Oman. A digoxin test is a blood test that your doctor can use to determine the level of the medication digoxin in your blood. Digoxin is a drug of the cardiac glycoside group. While the official upper limit of the therapeutic range is 2 ng/mL, there is some evidence to suggest that mortality in heart failure is improved at levels of 0.5 ng/mL to 0.8 ng/mL, although others suggest that 1 ng/mL to 2 ng/mL is an appropriate therapeutic range. Your dosage of digoxin (Lanoxin ®) may be adjusted no more often than every two weeks based on how you respond to the medicine and the results of your digoxin blood level. Normal therapeutic blood levels of digoxin (Lanoxin ® ) are considered to be between 0.5 and 2 ng per mL. Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results. Talk to your provider about the meaning of your specific test results. In general, normal values range from 0.5 to 1.9 nanograms per milliliter of blood. But the right level for some people may vary depending on the situation. Compounds in the digitalis family of glycosides consist of a steroid nucleus, a lactone ring, and a sugar. Digoxin is widely prescribed for the treatment of congestive heart failure and various disturbances of cardiac rhythm. A value of 40% is lower than normal. The basic cause for the diminished ejection fraction needs to be treated for the ejection fraction to improve. The basic cause for the diminished ejection fraction needs to be treated for the ejection fraction to improve. Digoxin takes approximately one to two weeks to reach a steady level in the blood and in the target organ, the heart. A test done at that time will reflect more accurately whether a person is receiving the right amount of digoxin.
