Scratch test for organomegaly. First do a "control". Won't hear scratching until very close to scope. Next put scope over organ (eg, spleen). Now you'll hear scratching when you reach edge of the organ (much farther from scope vs control). The organ "carries" the sound to scope.

Or get an ultrasound

Lots of reasons to examine before imaging, Janet, not to mention the fact that not every clinician in the world has access to an ultrasound machine.

As a doctor In acountry where you rely mostly on your clinical abilities rather than inmediately taking US/XRAY/CT, I do find this useful. As a pulmonology resident, we get used to exploring since day 1, based on the same fact we may (or may not) have an image soon, so THANKS!

@HaryaxPathak Pretty useful. Nearly 20 years ago, I picked up splenomegaly in a patient with diffuse systemic sclerosis and anaemia in the exam (using this) and stumped the examiners who had missed it. Very useful in not missing soft liver or spleen, when your life depends on it.

Isn't this ticklish and uncomfortable for patient?

Rakesh I haven't found that to be the case. But easy to stop if the patient is bothered by it.

I do it every day, but I don't know about sensitivity and specificity

According to this article, the technique has 90% specificity (10% false positive rate) when evaluating the liver. Not sure about sensitivity but would guess lower.

I met a consultant who was doing this for the past 13 years , and she was right every time
