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.
Your baby will then probably move on to pulling himself up. He may be able to stand holding on to something when he's between six months and 10 months old (Sheridan 2008, NHS 2013a) . From then on it's a matter of gaining confidence and balance. Most babies take their first steps by their first birthday. By the time they're 15 months old, most toddlers are walking unaided, though often with uneven steps (Harding 2014, Sheridan 2008) . Try not to worry if your baby takes a little longer. Some children don't walk until they are 17 months or 18 months old (NHS 2013a) . Babies who bottom-shuffle tend to walk later than babies who crawl (Sheridan 2008) .
