Can I fight my charges if the blood results weren't in by my first court day

Blood tests not being available by the first court date is not unusual.  The Court will merely keep resetting the case until the blood test results are provided.  Some courts do not allow you to enter a 'not guilty' plea at the first court date. That is because they have to get your case to a trial within 6 months of when you plead not guilty. That said, if you are in a county that does allow the not guilty plea to be entered at the first court date, then the trial must be within 6 motnhs of that date unless you 'waive speedy trial'.  So it gives you some leverage.
