The Pennsylvania site adjoins a research hospital and was chosen for its proximity to the so-called BOSNYWash cities of the north-eastern United States, and because the state government paid for "the lion's share" of the lab fit-out, said New Zealand chief executive David Darling.
A US chief executive was also appointed in April last year to lead development of the market.
The CLIA registration and consequent US commercial sales potential comes after 10 years and some $28 million of capital investment on Cxbladder and a range of other diagnostic tests to be rolled out in the future.
Some 60 per cent of the register is held by about 20 high net worth individuals, including the family of investor Peter Masfen, Warehouse founder Sir Stephen Tindall, and Dunedin sharebroker Eion Edgar.
The investment to date was equivalent to one or two years' typical cash burn in the US for a medical start-up, said Darling.
"The capability to build this business opportunity in the US off the back of the New Zealand business has been a significant factor in enabling this market channel to be delivered quickly and very cost-effectively."
The test is already available in Australia and New Zealand and will be launched soon in Spain, which has the highest global incidence of bladder cancer.
Pacific Edge intends to have its Dunedin laboratory CLIA-registered shortly, to take overflow work. It has already been used in the registration phase to test American urine samples, with courier arrangements between Dunedin and Pennsylvania still allowing the company to keep its promise of diagnosis within three to five days.
Pacific Edge shares were off 4 per cent in mid-afternoon NZX trading, at 73 cents, but have still gained 15.2 per cent in the last week and are up 85.4 per cent over the last three months.
