Screening tests explained! In this podcast we take a deep dive into the components, history, and utility of screening tests. Needless to say, things get pretty nuanced. As always, thanks for watching and sharing!

It's still baffling that this content is provided to us for free. Thankyou so much guys and gals.

Watched this a couple times and now downloaded it. Thanks for the help!

I may say that this podcast has an important message to take home: Medicine is far from perfect and medical professionals are prone to mistakes. However, as far as one's health is concerned there is no other reasonable choice than trusting medicine and medical professionals.

Second place to Jordan, Austin is #1 in our hearts.

1:08:32 I honestly do not agree with this take. I went to the doctor at 17 because I thought I was too short for my age compared to my brother ( not how it works I know). They discovered I had too low HGH, testosterone and hypothyroidism. I probably had symptons but at that point it was the "normal" for me. If I had not reacted on my physical height I would never have discovered this. My dose of Eltroxin is over the recommended dose by a good margin so its not like a little "nudging" of the numbers we are talking here

Excellent stuff. I was teetering on the verge of the rabbit hole, now I can happily walk away knowing I have a bigger chance of being hit by a truck on my way to the gym than discovering some rare disease or deficiency.

12:33 - "The sensitivity for BMI is just under 50%"
25:20 - Discussing BMI as a screening test and waist circumference as a follow-up confirmatory test.

Wait, so if BMI has very low sensitivity, doesn't that make it a very poor screening test? How does this work in practice? Is the BMI cut-off dropped in order to increase sensitivity at the cost of specificity when it is known that a follow-up waist measurement will be taken to confirm positive outcomes?

So, there's not really much use in getting a screening for prostate cancer? Did I get this right?

[masoudshokri]

In Iran, the cost of visiting a specialist and screening is quite low or at least is still low. I can say that these two scenarios happen almost often: 1. You go to a doctor and complain about your mild back pain. He or she doesn't touch you and orders an MRI, then you come back and another MRI is ordered. This may continue for a few visits, and 2. Somebody goes to a doctor and asks for a "full" screening because he recently feels tired (I mean the guy was dancing like a donkey last night, but he says he is always tired).

Jordan i love you please sign my prescription slips

Great video!! thanks!





Do you think vegans should test for b12 regularly or at all?

[wednesdayschild]

False positives are bad too. Anxiety and treatments are not benign. It ruins lives.

Wait a second, is Austin starting to out size the FeigenBOMB?

[robbyhoffmann]

SPin. SNout. Specificity in. Sensitivity out. I was under the impression that a positive high spec and high sen is a hard yes on what you are testing. Low sen low spec find a new test. Cluster testing is the best.
