So does this imply that women have lower levels than similarly exposed men?

I assume you mean due to menstruation? It highly depends on the individual, ethnicity, health, build, etc, but the amount of actual blood (vs mucus and non-blood fluid discharge) released in a cycle isn't as much as you might think. So the answer is probably "somewhat but negligibly so?"

I wonder how less effective double red donations are at this since they return your plasma to you during the donation. Sounds like plasma donations are the biggest bang for the buck, possible followed by single whole blood donations?

We should be able to test our blood for PFAS on a regular basis and our doctors should be able to let us know if we need to filter our blood. But PFAS testing is not the norm? Per a Tedx talk on this subject: https://www.nrdc.org/experts/anna-reade/pfas-blood-tests-nee... >> Unfortunately, a PFAS blood test is not a routine lab test that can be processed by your local lab and covered by your health insurance. In fact…

What do they cost?

If you were curious, a quick search gave me results in the range of $300-$400

Probably not, honestly. For most tests, the risks associated with a false positive outweigh the benefits of marginally earlier detection. Humans aren't precise machines, each person has different values and different value ranges for standard measurements - and asymptomatic deviations frequently mean nothing whatsoever. On the other hand investigations can be invasive, painful, risky and expensive. There's a reason m…

If they are run, the results could be uninformative (https://en.wikipedia.org/wiki/Base_rate_fallacy). Too many false positives could lead to risky treatment and be dangerous. Testing each positive again would still create false positives. I don't know the numbers in this case, but I wouldn't be surprised if accurate mass testing were impractically expensive.

I used to donate blood regularly. I would donate more regularly if I got a full blood panel with each donation. I've been quoted $600-2500. Surely you can comp that for me if I give you a pint.

According to the Red Cross website, donated blood is tested, too. https://www.redcrossblood.org/donate-blood/blood-donation-pr... So presumably they could just pass back the results of that test

It looks like it's just tested for different diseases. I'm more referring to my different blood metrics (cholesterol, CBC, CMP, hormones, etc)

In case anyone is curious, it appears a pint of blood in the US sells for $150--$300.

I just called Quest Diagnostics and they charge $679 w/out insurance for the PFAS panel [0].

In Poland you can get basic tests once a year if you ask beforehand.

The video in this comment provides some good examples for why the risks associated with a false positive can be pretty significant: https://news.ycombinator.com/item?id=31126368

This is the first example of detoxifying your body might actually be real.

Detoxification/cleansing has always been real, in the alternative and conventional/allopathic medical worlds. I don't know any school of thought that denies the benefits of cleansing (within reason); only those who disagree on how to go about it.
