These inter-laboratory comparisons demonstrate that&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;D/L&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;aspartic acid measurements are highly reproducible, whereas the enantiomeric measurements for the other amino acids show a wide variation between the three laboratories. At present, aspartic acid measurements are the most suitable for racemization dating of bone because of their superior analytical precision.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;ul id="issue-navigation" class="issue-navigation u-margin-s-bottom u-bg-grey1"&gt;&lt;/ul&gt;</dc:description>
