What are some of the better and less expensive progesterone testing labs?

I know that a blood sample has to be collected and sent by Fedex, and the result posted on the lab's website within 24 or less hours. I need quantitative result.

Is there a special Fedex service, or just any overnight am delivery OK?

I think I don't need a vet, or only minimal help from a vet tech. I will send the sample in myself.

What are some of the names , addresses and phone number or websites of such labs.

I live in California.

Thanks
