Through Babycheck, the genetic technique known as RT-PCR (real-time polymerase chain reaction) is used, we identify a chromosome DNA fragment and the result is known in 3 to 4 business days and its reliability index is greater than 99%.

You do not need to make an appointment or fast. It is performed from the 9th week of pregnancy.

The blood pregnancy test for greater reliability is done one day late.

It does not require fasting or making an appointment. The result is delivered in 1 hour.

STD CHECK FULL Comprehensive is for both men and women, covering 14 of the possible sexually transmitted infections in a blood and urine sample, which does not require fasting.

Technique used: MULTIPLEX-PCR This molecular tool has many advantages in the field of infectious diseases, among which we can highlight:

  • High sensitivity and specificity
  • Detection of possible coinfections
  • Significantly decreased window periods compared to serological tests
  • Simultaneous detection of multiple pathogens in a single reaction from a single sample
  • Rapid diagnosis that leads to the application of an early and effective therapy that reduces clinical complications associated with long periods of hospitalization
  • Sample type: urine and blood, collection kit

Detects:

  • Herpes Simplex 1 and 2
  • chlamydia
  • Gonorrhea
  • trichomonas
  • Mycoplasma
  • ureaplasma
  • Gardnerella
  • Papilloma
  • HIV
  • VDRL
  • B&C HEPATITIS

Urine, blood and/or lesion sample required

The DNA paternity test is a study that is carried out to demonstrate whether or not a man is the biological father of a child.

Its importance lies in the rights and obligations of the father. A person's DNA is always the same in every cell of the body. In sexual reproduction, DNA from the father and the mother is randomly put together, creating a unique combination of genetic material in a new cell. For this reason, the child's DNA is derived from the unique combination of the DNA of the two parents.

The maternal sample is not necessary to obtain a conclusive result in the vast majority of cases. However, it can help slightly increase the accuracy of the result.

He Human papilloma virus It has a significant number of species that are transmitted through sexual contact with an infected person.

This test allows us to identify HIGH risk oncogenic viruses and also low risk genotypes related to non-cancerous lesions.

HIGH RISK GENOTYPES:  16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68

(Detects genotypes 16 and 18 individually and/or a pool of 12 HIGH risk genotypes that includes 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68)

LOW RISK GENOTYPES: 6 and 11

At LSJ we deliver a kit so that you can collect the sample yourself and later bring it to the laboratory for the respective analysis.

Alzheimer's It is the most common cause of loss of cognitive functioning, that is: thinking, remembering and reasoning, to such a degree that it interferes with a person's life and daily activities.

ApoE Check It is a susceptibility or risk test, since it indicates whether there is an increased risk of Alzheimer's disease, without it being a diagnostic test for the disease.

The genetic technique known as RT-PCR (real time polymerase chain reaction) is used. Three APO E genes have been identified, namely E2, E3 and E4, with ApoE e4 being the one that has been associated with a greater risk of developing Alzheimer's disease (AD), therefore the number of carriers of this gene increases from 2 to 10 times the probability of developing Alzheimer's disease.

You do not need to make an appointment or fast.

  • Ask for a sterile container in the laboratory or buy it in the pharmacy.
  • Sexual abstinence must be maintained in the 3 days prior to sample collection.
  • It is advisable to clean the genital area and hands prior to taking the sample with plenty of soap and water, dry with a clean cloth or disposable towel.
  • The sample must be obtained only by masturbation directly into the sterile vial. It should not be picked up with a condom or through sexual intercourse.
  • The entire sample must be collected in the vial, without losing any of it.
  • The sample should NOT be refrigerated or exposed to high temperatures.
  • Record the TIME the sample was collected and bring it to the laboratory within one hour.

Celiacheck It is the most reliable test to find out if you or your family are or could be celiac.

  • Technique Used: Final Time PCR
  • Sample Type: Buccal Swab
  • Result: 1 Week

Used to evaluate ovarian function and fertility in women; There are several studies that have shown that the measurement of the levels of Anti-Mullerian Hormone it can be useful in predicting ovarian reserve (residual egg maturation potential) and establishing the probability of a woman becoming pregnant.

The HIV I/II test (antibodies and P24 antigen – latest generation) it must be obtained in the window period of 15 to 22 days (after the last risky sexual intercourse).

You do not need to make an appointment or fast. The result is delivered in approximately 12 hours.

Used to evaluate ovarian function and fertility in women; There are several studies that have shown that the measurement of the levels of Anti-Mullerian Hormone it can be useful in predicting ovarian reserve (residual egg maturation potential) and establishing the probability of a woman becoming pregnant.

AMH declines throughout a woman's fertile life, declines significantly near menopause, and ends up being virtually undetectable after menopause. The determination of the Anti-Mullerian Hormone can be useful in the evaluation of the fertile status of a woman and can predict the onset of menopause.

It is an analysis that is carried out to determine if the water is drinkable. The sample must be collected in a sterile container that can be given to you in the laboratory or can be purchased at any pharmacy (they are the same ones used for urine cultures). The minimum volume is 100 ml. The result takes approximately 48 hours.

The water analysis includes the following indicators: Escherichia coli, Total Coliforms. Every 6 months is how often water used for food preparation should be tested.
