It is normal to have blood on the brush for TCT, which is a type of brush used to remove shed cells around the cervix and inside the cervical canal to see if there are any pre-cancerous lesions of the cervix, so it is possible to bleed when brushing the cells, which is a normal phenomenon. If there is no bleeding at all, sometimes the number of exfoliated cells taken may not be enough, so the test results may not be accurate. This bleeding goes away after a day or so, so there is no need to worry and wait for the TCT results to determine the next step in treatment. If the test results are negative, there is no problem.
