The design pattern that best matches this data requirement between patient and lab test is the M:N strong relationship.

Here's why:

1. In this scenario, a single patient (1) can have multiple (M) lab tests. This is because at each doctor visit, a patient may be asked to undergo one or more lab tests.

2. On the other hand, a single lab test (1) can be associated with multiple (N) patients. This is because a specific lab test can be performed on many different patients.

Therefore, the relationship between patient and lab test is many-to-many (M:N), and it's a strong relationship because the lab tests are strongly dependent on the patients and vice versa.

The other options like 1:N strong relationship, Multivalued attribute, and Association do not accurately represent this relationship. A 1:N relationship would imply that one patient can have multiple lab tests, but each lab test is associated with only one patient, which is not the case here. A multivalued attribute would imply that the lab tests are an attribute of the patient, which is not accurate because they are separate entities. An association would imply a more general relationship, but in this case, the relationship is specifically many-to-many.
