Arturiano [62]

Answer:

The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.

Explanation:

When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.

One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.

It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.

The other options are not possible because:

Administering antibiotics should not raise lymphocyte levels.
There is no evidence of antigen attack.
Immunosuppressant drugs do not increase lymphocyte count.
