6-month-old baby's blood test results are mostly

Patient's question:

My baby is 5 months old. A few days ago, there were a few small red spots of subcutaneous peeling on his body. I took him to the Tianjin Maternal and Child Health Center for a check-up. He was seen by a dermatologist, and the doctor just said that his platelets were fine. I noticed that there were several items outside the reference range on the baby's report. Could you please help me take a look and see if there is any problem?

Besides the nurse not changing gloves when taking the blood, it felt a bit dirty. Also, it seems that there were only two red things. He used his fingers to make the baby's ring finger flush with blood, then wiped it with an alcohol swab a few times, pricked a small hole, squeezed the blood out, and then covered the needle hole with a dry cotton ball.
I'm so worried that I might have transmitted some disease to the baby. Right now, I'm most worried about HIV. I might be overthinking it, but it's just an unstoppable worry. Please give me a medical perspective on this. Thank you.
Regarding the assistance you need: Please help me see if there is a problem and what detailed tests should be performed.

Doctor's answer:

From the above blood test results, the child may have iron deficiency anemia or thalassemia. If it's difficult to supplement for the child alone, dietary therapy can be used, or the mom can supplement.
1. It is recommended to further conduct tests for ferritin saturation and serum iron. If abnormalities are found, follow medical advice for treatment. If iron supplementation is needed, both the mom and the child can consume iron-rich foods such as pork liver, chicken liver, egg yolks, lean meat, black fungus, and celery.
2. If there are no abnormalities in the above tests, further thalassemia genetic testing should be conducted. If abnormalities are found, targeted treatment should be administered.
