She claims there is a lack of blood tests available in Bracknell Forest, which GP surgeries are overseen under East Berkshire Clinical Commissioning Group (CCG).
The woman reportedly claims East Berkshire CCG has instructed their supplies to only allow urgent tests to be carried out.
She said: "This is very alarming as trying to obtain a blood test has become extremely challenging since October 2020 as hospitals only do appointments instead of walk in.
"This new initiative from the CCG only came into force a week ago. Personally I don’t understand the concept of this as blood tests are only ever ordered by the clinician for a reason. Are they trying to save money or are the laboratories over whelmed?"
