Those streaks are unlikely to be blood.
Sometimes old or altered blood can be brown.
Blood can come from vomiting
As the doctor has tested it & did not find any evidence of blood in it, you need not to worry.
Rapid Gastroccult test is available to see the presence of blood.
Probably doctor has done it.
Altered milk, mixture with bile can be a possibility.
