Could you give me some suggestions on how to convince someone to test blood sugar?

Test yourself: Be a good example. Demonstrate how easy it is, show the person that it is quick, and can give an accurate result immediately. Be able to explain the result, though! On a fasting specimen, less than 127 is normal and greater than 140 is concerning. Two hours after a meal, over 200 is diagnostic for diabetes. The fear of this knowledge may be what their hesitation is, so be prepared for the answer! ...Read more

How accurate is a 5 mins rapid hiv home test (blood) and when is it considered conclusive from last exposure (wks or mths)?

Screening test: It is a screening test. If it is positive, the result needs to be confirmed by a more definitive test. If the result is negative at less than 6 months after exposure, that does not rule HIV infection and testing needs to continue. See this site for safer sex guidelines:

Why would my tb test blood come back inconclusive?

Why would my tb test blood come back inconclusive?

It happens sometimes: Quantiferon TB blood tests look at one's white blood cells to see if they remember being in contact with TB germs. If her cells act healthily but don't react more excitedly when put into a simulated TB environment, that's a negative test. If her cells get very excited and active in a simulated TB environment, that's a positive test. Results that are "in between" are inconclusive. May retest later. ...Read more

Can you get HIV from dried blood on a latent needle used to test blood sugars? .

Can you get HIV from dried blood on a latent needle used to test blood sugars? .

Probably not: The cases in which HIV has been transmitted by needle have been from needles just withdrawn from HIV-positive patients' blood. I would be surprised if drying did not kill this very fragile virus. Having said this, anyone who uses a needle that may be contaminated is playing an extremely unwise game with their health for other reasons. This needs to stop and if applicable, law enforcement notified. ...Read more

Today I test blood and My ALT is 74 is this normal or not. And I am taking those tablets from last 7 days. (levofloxacin 250 mg....paracitamol 500 mg.

No reliable way: Zero alcohol, no ibuprofen. Maybe it'll drop. Maybe not. The key is that you understand a raised liver enzyme indicates a problem -- perhaps as simple as a medication allergy, beer, or lack of exercise; perhaps hepatitis B or C, hemochromatosis or Wilson's or autoimmune hepatitis waiting to kill you if it's missed. Be savvy, insist your physician explain the cause. ...Read more
