Starting Your Weight Training Program. â¢ Start with three sets of 15-20 repetitions. â¢ Training with high repetition sets ensures that the weights that you are using are. not too heavy. â¢ To avoid injury, performing any weight training exercise to the point of muscle. failure is not recommended. â¢ âMuscle failureâ occurs when, in performing a weight training exercise, the. muscle is no longer able to provide the energy necessary to contract and move the. joint(s) involved in the particular exercise. â¢ Joint, muscle and tendon injuries are more likely to occur when muscle failure. occurs.
A blood sample for a TSH level is drawn by a phlebotomist or nurse from a vein in your arm or hand. The blood sample is sent to a laboratory for processing. Fasting is not required before having a TSH level drawn. Results. According the MedlinePlus.com, a normal TSH level is between 0.4 and 4.0 mlU/L. If you have a thyroid disorder and are receiving treatment, your physician may want to keep your thyroid level between 0.5 and 3.0 mlU/L. Considerations. Different laboratories may have slightly different normal ranges for a TSH level.
Normal and Abnormal Test Results. Although various professional health bodies have specified the normal range for TSH to be 0.4 - 4.5 mIU/L in the past, new regulations recognize that this range is too wide. Currently, the standard reference range for TSH is 0.4 - 3.0 mIU/L. However, clinical data show that 95% of euthyroid patients fall in the range 0.4 - 2.5 mIU/L. In addition, adults with TSH levels over 2.0 mIU/L are likely to develop hypothyroidism later in life. Therefore, the ideal range of TSH is 0.4 - 2.0 mIU/L. Children, generally, have higher TSH levels than adult. The National Academy of Clinical Biochemistry recommends 1.3 - 19 mUI/L for newborns. These values drop with age and by the first year, TSH level for an infant should be between 0.4 mIU/L and 7 mIU/L.
