British NHS personnel are sent on seven-hour trips to Scotland to be tested for coronavirus.
The government website gave frontline workers appointments in County Durham to Edinburgh and Perth.
They would need a 400-mile journey to get there and back.
The bizarre appointments come despite the army recently setting up testing stations in Bishop Auckland and Dalton Park in Co Durham.
Kevan Jones, Northern Durham MP, described the situation as “chaos”.
He said: “The idea that people are sent to Edinburgh shows the sloppy nature of the national screening program.
“The government has made the decision to work with the private sector and is trying to control things nationally rather than working with the local government and local health funds.
“The Prime Minister said that 200,000 tests per day will be performed by the end of the month. It is not possible to reach the goal with this chaos.
“The serious point here is that he is talking about lifting part of the blockade Monday and the government has no idea where the people who are proving positive are.
“This does not trust the public.”
Jones said that lifting the restrictions without knowing where positive cases refer is a second wave of coronavirus cases inevitable.
He added: “You have hard-working health workers and NHS staff who are putting their lives at risk but are unable to get tested.
“This is unjustifiable.”
A spokesman for the Department of Health and Social Care said: “In addition to creating a national network of drive-in test sites, we have also introduced home test kit delivery and distributed mobile test units operated by the military. “.
Meanwhile, the government has missed its 100,000 test target for the sixth consecutive day
Environment Secretary George Eustice said 97,029 tests were conducted in the 24 hours at 9 am yesterday, compared to 86,583 on Thursday.
Asked why the UK had not tested capacity for six consecutive days and reported delays of up to 10 days in recovering results, Eustice said: “You will have a few days of excess testing where people have not come forward to support in some areas and you will have other areas where you don’t have enough capacity for local demand. “
