Is there a list of the most abundant small molecules in human serum?

Excluding large proteins and cells.

30 seconds searching on wikipedia yields: https://en.wikipedia.org/wiki/Reference_ranges_for_blood_tests

Again, most of my posts are well thought and researched, that a simple google search won't answer them.

I am pretty sure ATP, NADP are in adundance in blood, but your list doesnt have them.

I'm pretty sure they are not.
"Plasma  concentrations are three orders of magnitude lower than
within the erythrocytes, partly due to the rapid breakdown of ATP; only 1% of ATP is detectable in whole blood 40 s
after bolus injection."

Well, you will be surprised that it's more than oxygen concentration in blood.

[chiralSPO]

You may be surprised that oxygen isn't transported as free O₂ in the bloodstream. See: hemoglobin.

I beg to differ.
Googling "list  "most abundant" "small molecules" " human serum""
gets you
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3040193/
which cites this
http://www.serummetabolome.ca/
which, in turn leads you to this

"The Serum Metabolome database is a freely available electronic database containing detailed information about 4651 small molecule metabolites found in human serum along with 10895 concentration values. The data tables may be sorted and searched by concentration values and ranges. "

When you make your "extensive list" of the most abundant small molecules in blood serum, most of the list entries will be H₂O.

How do you do the sorting per concentration?

I don't.
If I wanted to , I'd stuff the relevant data into something like excel, and get that to sort it
