Quick test description:

It is used to determine karyotype by classical cytogenetic methods to determine numerical and structural chromosomal aberrations (deviations) of the gamete donor.

Test details:

The reason for collection is to determine the karyotype of the patient or gamete donor tested. During cytogenetic examination of karyotype from blood, we culture T cells. We stimulate T-cell division by plant lectin, phytohaemagglutinin (PHA).  Using microscopy, we evaluate the number and structure of individual chromosomes. We do not perform blood sampling after transfusion (safe time interval of at least 6 months) due to the influence on the test results, as the karyotype could correspond to the karyotype of the blood donor, not the patient.

Indication

abnormal patient phenotype, growth and development problems in the patient, mental retardation of the patient or in the patient’s family, stillbirth and neonatal death, repeated spontaneous abortions, infertility or repeated IVF failures, positive family history of chromosomal rearrangements
