The National Institutes of Health says that if a person has been prescribed medical treatment for hypoxemia or if they’ve had a diagnosis of anorexic disorder, they should be taken to a doctor for a blood test to see if they have an elevated level of the amino acid glycine.
If they do, they can be treated with a medication to increase their levels of the chemical.
But if they don’t, they shouldn’t be tested because they can develop anorectic symptoms, the agency said.
Anorexia is a condition where the body’s body can’t properly metabolize food, so it can’t function properly.
The symptoms include excessive weight loss, lethargy, sleep disorders and fatigue.
The NIH says that, if the person hasn’t received treatment for the condition, they need to be tested.
The testing is done in a hospital.
If the person has met the NIH criteria for an elevated blood glycine level, they could have an eating disorder.
If not, they would be prescribed anoreoxidizing diet.
A number of states are making it more difficult to get tests for an eating disorders diagnosis.
In a statement, the NIH said it is monitoring the new guidelines, but the agency recommends that patients not be tested until they’ve already been diagnosed with an eating problem.
“We also advise that a person should not be screened for an anxiety disorder until they have been diagnosed,” said NIH spokeswoman Amy Phelan.
“This is important for people with a history of anxiety disorders and other mood disorders.”
An American Psychiatric Association spokeswoman told ABC News that the association has been working to ensure that people are not screened for eating disorders.
“If a person is diagnosed with a diagnosis, the first step in screening is to get a mental health evaluation, and this is critical to get this diagnosis,” said Ashley K. Crain, a clinical psychologist who works at the American Psychiatric Assn.
at the National Institutes for Health.
“Then, if needed, it is important to get tested.”
The National Institute of Mental Health, which has been the agency for the new guideline, says that people who have not been diagnosed are not required to be screened.
But they can’t go without tests, Phelin said.
