OK I plugged in my numbers into this, and the calculator said:
Bioavail T = 180ng/dL
Free = 6.06 ng/dL
my labs for B.A = 93.9ng/dl (range 110-575)
My labs for Free = 37.7pg/nL (range 46-224)

Yes I was able to reproduce your numbers using the calculator.
TotalT.....434 ng/dL (ref range 250-1100)
SHBG ..... 51 nmol/L (ref range 15-49) (HIGH, get the LEF stuff or Chrysin cream, as much as you can)
Albunim,Serum .....5.5 g/dL (ref range 3.6-5.1)
Free Testosterone =6.06 ng/dL = 1.40 %=60.6pg/dL
Bioavailable Testosterone=180 ng/dL = 41.5 %
But QuestDiagnostic calculated:
FreeT .....37.7 pg/mL (ref range 46.0-224.0)
BioAvail T..... 93.9 ng/dL (ref range 110-575)
Now, recal people complaining of huge error in this 1990 science level, basic calculator. They claim that the old knowledge assumes singular SHBG molecule while it is "dual".
Righ here it is written:
CalcV was reported to overestimate BAT by a factor of 1.5–2.2 . Moreover, CalcV was first proposed
in 1999 w8x and is, naturally, based on the biochemists’ view of the SHBG molecule in the 1990s; but
the view of this molecule has changed, step by step, in recent years
I am assuming that Quest knows what they are doing.
Until further information is available, I am assuming that the unforunate people who are not able to use Quest Diagnostic service, are just plain unfortunate.
Ok, I have my blood work in front of me, let see what happen.
Testosterone, Free, Bio/Tot
Testosterone Total 456 ng/dL (250-1100)
Testosterone Free 91 pg/mL (46.0-224.0)
Testosterone Bioavailable 179 ng/dL (110.0-575.0)
SHBG 20 nmol/L (23-38)
Albumin, serum 4.3 g/dL (3.6-5.1)
From calculator I get
Free Testosterone=12.2 ng/dL = 2.68 %=122pg/dL
Bioavailable Testosterone=286 ng/dL = 62.7 %
We could use more real life examples,
but for now, I would say the more SHBG one have the bigger the error.
All above assumes that your nombers are from Quest.
I suggest that few more people with Quest BAT blood analysis post their results.
I would calculate the spread and possibly we could figure out some reasonable correction factor.

I have my own BioAvailable T calculator, its called the "Wood-Ometer", much more exact science on how I feel. I test it every morning and night, and its a free test as well.
