The range for a normal test result depends on your age and gender. For adults younger than 40, normal levels are typically in the range of: 107 to 139 mL/min or 1.78 to 2.32 mL/s (SI units) for men. 87 to 107 mL/min or 1.45 to 1.78 mL/s (SI units) for women. Creatinine clearance rates go down as you age.For every decade after age 40, a normal test result is 6.5 mL/min less than the numbers above. For newborns, the normal range is 40 to 65 mL/min. An abnormal creatinine clearance rate may mean you have a problem with your kidneys.Or it may mean a problem somewhere else in your body is affecting blood flow to the kidneys.ealthy kidneys remove creatinine from the blood. It then passes out of your body through urine. The creatinine clearance test usually compares the creatinine level in a 24-hour urine sample with the creatinine level in your blood. This tells your doctor how well your kidneys are working.
According to the Denver II Developmental Assessment milestone's chart, infants can usually: 1  stand, holding on to things between 6 1/2 to 8 1/2 months. 2  pull to a standing position between 8 to 10 months. 3  stand for about 2 seconds between 9 to 11 1/2 months.  stand alone between 10 1/2 to 14 months.
One of the first developmental milestones that new parents look forward to is the day their baby learns to sit up. Most babies will learn to sit by themselves somewhere between 6 and 8 months, however, it can happen as early as 4 months or as late as 10 months with no cause for alarm. As soon as your baby can support and control her head and has mastered rolling from back to belly, she can start learning to sit.
