Hi and thanks for the query,
It would be very unlike in this particular situation situation attribute any changes in Serum Glycated hemoglobin
and triglycerides to Doxycycline. Serum HbA1c
levels give ab approximate behaviour of blood glucose
for over a period of three months. In your case, with no history of liver disease, it would be very unlike that this drugs metabolism
changes these parameters, provided also that we do not have any signs of acute liver damage
Its worth noting that results you present are all still within normal limits, and small changes should normally be observed during measurements, due to normal physiologic variations and tests that are used. Remember the tests or reagents in testing usually differ and the techniques might also differ. It is there fore not unusual to note different results.
However, when results are actually abnormal, it is necessary to consult your treating physician, for a clinical assessment and control of the specific tests.
Thanks as I hope this helps,
