FAQ (FREQUENTLY ASKED QUESTIONS)

Do I need a request form from my doctor for SANCO testing?

We recommend the SANCO Test to be ordered by a physician. Please check with the chosen local SANCO provider, whether the doctor is on the spot or talk about the test with your doctor.

Which version of the SANCO should I choose?

The SANCO Test detects trisomies and monosomies of all 23 chromosome pairs as well as deletion and duplication syndromes of at least 7 million base pairs. Thanks to this, the scope and resolution of the test is comparable to the karyotype of amniotic fluid testing (from amniocentesis).
The SANCO plus Test, offered by Genomed only in the Polish territory, is designated only for specific cases. It is the right choice for patients who want to perform tests for 5 selected deletion syndromes. Some deletions detected in the SANCO plus Test may be less than 7 million base pairs and for this reason will not be detected in the SANCO test (22q11, 4p16.3 and 15q11,2 deletions). In other cases we recommend performing the SANCO Test.

How much does the SANCO Test cost?

We provide two options of the test: SANCO and SANCO PLUS. SANCO PLUS is more expensive and turnaround time is longer.
The prices available for patients in the Genomed Health Care Centre: 2,000 PLN (SANCO) and 2,500 PLN (SANCO PLUS). This price includes a short consultation prior the test.
Genomed does not monitor the prices of the SANCO Test in the partner facilities. Prices may vary between facilities/clinics in Poland. Sometimes this is due to the fact that the price includes a visit or an ultrasound examination.

When is the earliest possible time for performing SANCO prenatal test?

We recommend performing the SANCO Test between 10 and 24 weeks of pregnancy. There are no contraindications for the SANCO test in the advanced pregnancy (even after the 24th week of pregnancy), however, the patient should be aware that after obtaining a bad/unfavourable test result, she should decide on invasive testing to verify the risk and in advanced pregnancy it is not always possible.

What does the visit and blood draw look like? Do I have to be specially prepared for it?

The patient should have an ultrasound result of her current pregnancy or perform an ultrasound during the SANCO appointment. If other screening tests or pregnancy karyotype tests were performed, please take the results of these tests with you. You need to make sure how much the visit will cost in advance and what it includes, and whether you need to schedule an appointment.
SANCO is a genetic test, so its performance should be preceded by consultation with a specialist in genetics or gynecology and obstetrics. Following issues should be discussed during the appointment: the patient's procreative history, genetic diseases in the family and the results concerning the current pregnancy. Before testing the patient should become familiar with all the conditions and limitations of the test, and sign a Consent Form.
The procedure is analogous to taking blood for morphological testing. However, the test tube differs (it has a camo plug), because the blood cells have to be protected against disintegration and contamination of the cell-free DNA. The analysis itself requires 10 ml of blood sample. The testing doesn’t require fasting. As before the usual blood draw, it is good to drink extra liquid.

How is blood collected for the test?

10 ml of venous blood are collected. The procedure is analogous to taking blood for morphological testing. However, the test tube differs (it has a camo plug), because the blood cells have to be protected against disintegration and contamination of the cell-free DNA. The analysis itself requires 10 ml of blood sample. The testing doesn’t require fasting. As before the usual blood draw, it is good to drink extra liquid. 

Is it true that the RHD Test can be performed with the SANCO Prenatal Test?

YES, it is possible, if the patient is Rh- and has no anti-D antibodies. Both tests are ordered on one form, two blood tubes are taken, and the price of the child's RHD testing is lower than when the RHD Test is ordered separately. 

How long would I wait for the test result?

The standard issuing time is a few days, and the maximum waiting time for feedback is 5 business days for SANCO and 12 business days for SANCO plus, from the date of delivery of the sample to the Genomed SA Laboratory (Warsaw, Poland). Due to the sensitive data security, Genomed employees do not provide any information about the progress and results of the testing by e-mail or phone. The SANCO Test result can be picked up at the clinic/facility, where the blood donation has been drawn performed and is available on the dedicated on-line platform immediately after it has been issued. Any information about the ongoing testing should be provided to the patient by the local SANCO provider. If you perform testing directly at Genomed, you will be informed by Genomed’s employees that you may pick up your result.

How many deletion/duplication syndromes are detected in the SANCO Test?

Exactly that amount as in the amniotic fluid testing (karyotype) from amniocentesis. On the "TEST RANGE" page, you can find several examples of common and known deletion syndromes, such as 1p36 deletion, Cri-du-chat syndrome (5p), 12p duplication, 16p11.2-p12.2 deletion, Pallister-Killian syndrome (12p isochromosome), 16p11.2-p12.2 duplication, cat eye syndrome (22pter-22q11 tetrasomy), 2q33.1 deletion. The SANCO Test also detects all other deletion syndromes larger than 7 million letters. There is no single statistic that shows the exact number of known deletions larger than 7 Mbp and therefore Genomed does not publish such a list.

Why deletions/duplications less than 7 Mbp (including DiGeorge syndrome) cannot be detected in the SANCO Test?

The SANCO Test is performed in Poland. Test resolution for deletion/duplication syndromes is defined by the test producer. The ability to detect deletions/duplications smaller than 7 Mbp is possible by increasing the sequencing coverage, which is associated with a much more expensive and longer analysis. Such analysis is available in the SANCO plus Test.
