What is the purpose of WellNest?

WellNest helps you store and organize vital medical information, such as blood type, genotype, allergies, and emergency contact details, for quick access during emergencies.

What is BMI?

The full meaning of BMI is Body Mass Index. It is a measure used to classify underweight, normal weight, overweight, and obesity based on a person's weight relative to their height. It is calculated using the formula: weight(kg)/height(m)2. See Health Calculator

What are the different blood types?

The main blood types are A+, A-, B+, B-, AB+, AB-, O+, and O-. They are categorized based on the presence or absence of specific antigens.

What do the genotypes AA, AS, and SS mean?

Genotype refers to the genetic makeup of an individual. AA is normal, AS is a carrier of the sickle cell trait, and SS indicates sickle cell disease.

What is blood compatibility?

Blood compatibility determines who can donate or receive blood. Here’s a quick guide:

• O- is a universal donor and can donate to all blood types.
• O+ can donate to all positive blood types (A+, B+, AB+, O+).
• AB+ is a universal recipient and can receive from all blood types.
• A and B types can donate or receive based on their specific Rh factors (+ or -).

What is genotype compatibility?

Genotype compatibility is crucial for avoiding genetic disorders like sickle cell disease in offspring. Here’s a guide:

• AA + AA: Compatible (no risk).
• AA + AS: Compatible (carrier risk).
• AA + SS: Compatible (offspring carrier of S).
• AS + AS: Risk of sickle cell disease (25% SS).
• AS + SS: High risk of sickle cell disease (50% SS).
• SS + SS: 100% risk of sickle cell disease.
