Cow's milk allergy is an immune system reaction to proteins found in cow's milk, particularly casein and whey proteins like beta-lactoglobulin. It is caused by the immune system mistakenly producing IgE antibodies against milk proteins, triggering allergic reactions ranging from hives and digestive upset to life-threatening anaphylaxis. The Food Allergen Profile IgE With Component Reflexes is the most important test for diagnosis because it detects specific IgE antibodies to cow's milk proteins.
Cow's milk allergy is caused by the immune system mistakenly identifying milk proteins as harmful invaders and producing IgE antibodies to attack them. The two main protein groups in cow's milk that trigger allergic reactions are casein (found in the solid part of milk) and whey proteins like beta-lactoglobulin and alpha-lactalbumin. When someone with cow's milk allergy consumes milk or dairy products, their immune system launches an attack against these proteins, releasing histamine and other chemicals that cause allergic symptoms ranging from mild skin rashes to severe anaphylaxis.
The Food Allergen Profile IgE With Component Reflexes is the most important test for cow's milk allergy because it detects specific IgE antibodies to cow's milk proteins, confirming whether your immune system is truly allergic to milk. This comprehensive blood test measures IgE levels to cow's milk (F2) and can identify which specific milk protein components are triggering your reactions, helping predict the severity of allergic responses and risk of anaphylaxis. For additional insight into specific protein sensitivities, the Beta lactoglobulin IgG test can measure immune responses to this major whey protein, which is particularly useful for understanding reactions to processed dairy products where this protein remains present.
You should get tested if you or your child experiences symptoms like hives, swelling, vomiting, diarrhea, wheezing, or difficulty breathing within minutes to hours after consuming milk or dairy products. Testing is especially important for infants and young children who develop eczema, persistent digestive problems, or failure to thrive, as cow's milk allergy is one of the most common food allergies in early childhood. You should also consider testing if you have a family history of food allergies or other allergic conditions, or if you have experienced any severe reaction to dairy that could indicate risk for anaphylaxis.
What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
