Pros:
1. It offers insight - reading DNA sequence from start to finish to seek out disorders or mutations
2. A relief from uncertainty
3. Take action - knowing whether you have diseases at the early time helps you to take action early
Cons:
1. Trigger emotions: results can cause depression and anxiety for people
2. Expensive: genetic screening can be costly

Genetic screening is a type of testing that identifies changes in genes, proteins, and chromosomes. The results of screen testing can tell a person if they have a genetic condition or find out if that person can pass the condition on to another.

1. Newborn screening: used just after birth to identify genetic disorders that can be treated in early life.

2. Diagnosis testing: used to identify or rule out a specific genetic or chromosomal condition

3. Carrier testing: used to identify people who carry one copy of gene mutation that, when present in two copies, causes a genetic disorder

4. Prenatal testing: used to detect changes in fetus’s genes and chromosomes before birth.

5. Preimplantation testing: a specialized technique that can reduce the risk of having a child with a particular genetic or chromosome disorder

6. Predictive and presymptomatic testing: used to detect gene mutations associated with disorders that appear after birth, often late in life

7. Forensic testing: uses DNA sequences to identify an individual for legal purposes

1. Step 1– In the doctor's office: Doctor will talk to you about about the test, take your sample and send it to lab

2. Step 2– Prepare your DNA: To find the cause of a disease, the way the lab looks at your DNA will depend on the type of genetic test your doctor ordered.

3. Step 3– Sequencing your DNA: read your DNA and look for variants (changes) in the DNA

4. Step 4– Analyzing your DNA: Computers are used to compare your DNA to all of the DNA in the human body (the human reference genome)

5. Step 5– Interpreting your DNA: A team of experts talks about and analyzes your results

6. Step 6– Receiving your results: The lab will give the written results back to your doctor or genetic counselor
