Brief Answer:
Skin test is more reliable.

Detailed Answer:
Thanks for your question on Health Care Magic.
I can understand your concern.

Skin test is more reliable as compare to blood test.

Actually skin test is done by specific allergen and it is highly specific.
No chance or false negative result.

Blood test can give false negative results.

So skin test is always more confirmatory as compare to blood test.

Hope I have solved your query. I will be happy to help you further.

Wish you good health.
Thanks.
