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.
Give your baby lots of tummy time as well so she can practice pushing up and strengthening her abdominal muscles, which will also help her to eventually pull up and stand. Most babies start pulling up on their own and then cruising around furniture between 9 and 12 months. If your baby doesn't seem to be making any progress over the next few weeks or months, express your concerns to your pediatrician, who may refer you to a physical therapist to help boost your baby's motor skills.
