How accurate is capillary refill test for pad or dvt?

How accurate is capillary refill test for pad or dvt?

Not the best.: Capillary refill is essentially an observation of how long it takes for blood to return into small vessels usually in the nail beds or feet. It is not accurate and it is not used for dvt. It is observed in pad. There are much more specific, informative and diagnostic tests for both DVT and PVD such as duplex scans and abi's and even cta's. ...Read more

Would 5 or 6 drinks consumed one time in 100 days read above the cut off levels for nail etg test?

Would 5 or 6 drinks consumed one time  in 100 days read above the cut off levels for nail etg test?

I doubt it, no etg: Drinking on a single occasion should not spike etg levels, which are more accurate in detecting differences in low, medium and high levels of drinking on a regular basis. The study looked at diiferences between subects who drank from 10 to 30 drinks per week, and for those who drank at those levels, etg levels corresponded to the low, medium ang high level groups. ...Read more

If I have nail change does it mean I have HIV been having nail change for long time but test negative 178 days?

If I have nail change does it mean I have HIV been having nail change for long time but test negative 178 days?

Not necessary at all: Why do you assume that if you have a "nail change" that you have acquired HIV. What nail change do you have. There are several associated with HIV but these are also changes seen in many patients with chronic illness. There isn't a pathognomonic nail change which defines HIV. Hopefully you take some reassurance. But if you are worried please seek the input of your doctor. ...Read more

I was completely sober for almost 100 days....then I drank approx 6 drinks on one ocassion. Would that show up on hair or nail test?

Yes it can: It could show up. It would depend on the drug screen used in the testing. Nails take up to 6 months to grow out fully. So, the evidence is there. Testing is quite sophisticated, and if ethanol is included is the screen used, it can be seen. ...Read more

My 3yr old has been chronically tired so I took her 2 a paediatrician. He found nothing. Ijust noticed her capillary refil time is very long 9 seconds?

My 3yr old has been chronically tired so I took her 2 a paediatrician. He found nothing. Ijust noticed her capillary refil time is very long 9 seconds?

Odd statement: I would expect a kid with a 9 second capillary refill time to be near death. Perhaps your definition of the maneuver is quite different than mine. I doubt that would be the case in a kid who is functional at any level. If you are concerned the doc has missed something find another and get a second opinion. ...Read more

How far does the testing for a hair follicle and nail drug test go back? I am getting conflicting answers on both tests. I have been told 90-120 days or longer for hair follicle depending on length of hair and up to 1 1/2-2 1/2 years for nail testing.

Varies: The hair testing numbers are about right, with hair growing about 1/2 inch per month, and the average length of hair tested being 1 1/2 inches, which is about 90 days. Nails give 4-6 months at usual lengths. If you never cut them, or have very very long nails, you could get 1-2 years, but that is not common. ...Read more
