Objective To analyze the results of laboratory tests and laboratory network tests of iodine deficiency disorders at all levels in Heilongjiang Province and to provide reliable laboratory quality assurance for the monitoring and prevention of iodine deficiency disorders. Methods The results of the external quality control test of laboratories of iodine deficiency disorders at all levels in Heilongjiang Province from 1999 to 2011 were analyzed. Results Provincial salt iodine, urine iodine laboratory for 13 consecutive years feedback rate and pass rate of 100%. The feedback rate of municipal salt iodine and urine iodine laboratory has reached 100% for 8 consecutive years since 2004. The passing rate of salt iodine rose from 90.9% in 2000 to 100% in 2011. The passing rate of urinary iodine was increased from 1999 50% up to 100% in 2011. The feedback rate and pass rate of county salt iodine laboratory rose from 63.3% in 1999 and 63.2% in 1999 to 100% in 2011 respectively. Conclusion The laboratory network of iodine deficiency disorders at all levels in Heilongjiang province is in good condition. All the quality control tests have been passed, which can provide reliable laboratory quality assurance for the monitoring and prevention of iodine deficiency disorders.
