Brief Answer:
STOP HRT, NO FURTHER TEST NEEDED.

Detailed Answer:
Hello XXXXXXX
Thanks for writing to us with your health concern.
To answer your last question first, there is no way more reliable than genetic testing that can accurately calculate your risk for VTE.
HOwever, the number is just a number, and it estimates your CHANCES of having VTE, but it is a high number.
You had the hysterectomy 35 years ago, I would appreciate it if you let me know since how many years you are taking the HRT.
It is not advisable to take HRT beyond 3 - 5 years, and after 60, it is definitely risky to continue taking it, coupled with your genetic predisposition for VTE.
Hence, again, there is no logic for further VTE testing, as you already have enough reasons to stop your hormone therapy.
Hence, I would ask you to taper off your estrogen, ultimately stopping it.
There are 2 ways to do this.
50 % of women are lucky enough to get away with stopping hormones cold XXXXXXX
For the remaining 50 % , the menopausal symptoms come back with a bang if HRT is stopped cold XXXXXXX for them tapering is an option.
So, you could try stopping your estradiol, and then if you are not working fine without it, then go for plan B.
Plan B involves tapering your dosage.
You can take your tablets every alternate day for 2 weeks, then every third day for 2 weeks, and so on, till you ultimately stop them.
Another feasible option is to take half your pills daily for 2 weeks, then gradually half a pill every alternate day and so on till you totally stop.
Of course, you might experience difficulties if you have been on the hormones for a very long time, so be mentally prepared and fortify yourself.
Upping your dairy products intake, exercising regularly, taking enough calcium and vitamin D will help.
All the best, I hope this answer helps you.
Please feel free to ask for further clarifications.
