HCG Stimulation Test<\/h3>

LABOKLIN Service ID: 1360<\/span><\/p>
Diagnosis<\/strong><\/td>

  • Detection of endocrine active tissue of the gonads (ovary, testis).<\/li>
  • Cryptorchidism<\/li>
      <\/p><\/td><\/tr>
Material<\/strong><\/td>

serum 2 x 0.5 ml<\/p><\/td><\/tr>

Execution<\/strong><\/td>

dog (male\/female), stallion:<\/strong>

  • first blood collection = baseline value (testosterone: male dog and stallion, oestradiol: female dog) <\/li>
  • injection of 500 IU of HCG (Ovogest\u00ae)\/dog i.v. respectively 5000 - 10000 IU\/horse i.v. . <\/li>
  • second sample after 1 hour = stimulation value<\/li>
  • (dog: perhaps additional sample after 30 minutes<\/li><\/ul>
    rabbit (male):<\/strong>
    • first blood collection = baseline value (testosterone)<\/li>
    • injection of 250 IU of HCG (Ovogest\u00ae)\/animal i.m.<\/li>
    • second sample after 1 hour = stimulation value<\/li><\/ul>
      rabbit (female):<\/strong>
      • first blood collection = baseline value (progesterone)<\/li>
      • injection of 250 IU of HCG (Ovogest\u00ae)\/animal i.m.<\/li>
      • second sample after 5 \u2013 7 days = stimulation value<\/li><\/ul><\/p><\/td><\/tr>
Parameter<\/strong><\/td>

dog, cat, horse:<\/strong> testosterone (male) or oestradiol (female)
rabbit:<\/strong> testosterone (male) or progesterone (female)<\/p><\/td><\/tr>

Species list<\/strong><\/td>

dog, cat, rabbit, horse, donkey<\/p><\/td><\/tr>

Duration<\/strong><\/td>

1 day<\/p><\/td><\/tr>

Assessment<\/strong><\/td>

  • In most cases, the determination of the AMH level (see category Endocrinology \/ Tumour Markers) provides comparable information.<\/li>
  • male dog: <\/strong>post-stimulation testosterone concentrations > 1.0 ng\/ml indicate that there is testicular tissue. <\/li>
  • stallion:<\/strong> Testosterone concentrations between 0.05 and 0.1 ng\/ml after stimulation are considered as borderline and need further clarification \u2013 e.g. by determining the anti-M\u00fcllerian hormone. Higher values indicate the existence of testicular tissue.<\/li>
  • rabbit: <\/strong>Stimulation values of > 1 ng\/ml of testosterone or > 4 ng\/ml of progesterone indicate hormone-producing tissue.<\/li><\/p><\/td><\/tr>
Remark<\/strong><\/td>

  • The HCG Stimulation Test (as well as the GnRH Stimulation Test with the test number 2281) can be used to detect endocrine active ovarian tissue \/ ovarian remnant syndrome in female dogs. It is a determination of oestardiol. The stimulation of oestradiol secretion is strongly dependent on the cycle status. Significant increases in concentration are expected in the oestrus and late anoestrus.<\/li>
  • The HCG stimulation test can also be carried out on male donkeys.<\/li><\/ul><\/p><\/td><\/tr><\/table>\n","protected":false},"excerpt":{"rendered":"
