The first card is the Four of Wands, which indicates a current situation of stability and peace. This can be interpreted as a sign that you are doing the right things for your health, but not enough to keep it in good shape in the long run.
The second card is the reversed Ace of Wands, which indicates an obstacle. You may be so busy with your job or other responsibilities that you are unable to take care of your health as well as you should. It could also mean that you are not very motivated to go for regular blood tests.
Finally, the third card is the reversed Seven of Wands, which offers advice: try to find the balance between your professional and personal life so that you can take care of your health. You will find more benefit in investing time and energy in the prevention of your health rather than in the treatment of the disease.
Bottom line, yes according to the papers you need to have regular blood tests done to maintain your health. The current situation suggests that you may not be diligent enough to take care of your health, while the obstacle is lack of time or motivation to do so. The advice is to find a balance between work and personal well-being so that you can take better care of yourself.
