Concerns Regarding Newborn's Amino Acid Lab Results

7/29/2025, 10:20:25 PMMale25-34

We've recently received laboratory test results for our infant daughter, but we won't have the opportunity to discuss them with our doctor until tomorrow. We would be grateful for any insight that could either alleviate our worries or help us understand if there's a cause for concern. The initial screening indicated an elevated level of tyrosine; we aren't aware of the specific value, but we've been informed that it likely doesn't reflect the most severe form of tyrosinemia. Consequently, further amino acid tests were conducted. The latest results confirmed an increased tyrosine level at 226. Fortunately, the accompanying note suggests that this condition is likely a benign, transient form of tyrosinemia, which does not appear to be alarming given that the level isn't excessively high. Additionally, the tests indicated increased levels of serine (315), hydroxyproline (83), aspartic acid (34), and hydroxylysine (5). AI insights suggest that these elevations might not be of significant concern and could be related to her slightly premature birth at 37 weeks and 6 days. Conversely, a notable concern arises from the carnosine measurement of 11, where the reference range is under 3. The AI has confidently asserted that this indicates carnosinemia, a rare condition affecting only about 30-40 individuals globally. I fear that the overwhelming information from the internet is heightening our anxiety, and I know we should rely on professional medical advice, yet the stress persists. The AI remains convinced that this is the sole explanation and dismisses the possibility of an error in this result. If anyone has knowledge about this situation, your thoughts would be greatly appreciated. Our newborn is currently two weeks old (the lab tests were taken around the one-week mark), and she is being breastfed, if that information is relevant. Thank you in advance for your assistance!

I understand that receiving lab results for your newborn can be incredibly stressful and worrying, especially when there are elevated levels of certain amino acids. Let’s break this down to help clarify the situation and provide some actionable steps to alleviate your concerns.

Main Points:

  1. Elevated Tyrosine: The levels indicate a likely benign condition, transient tyrosinemia, rather than severe tyrosinemia.
  2. Other Amino Acids: Slight increases in other amino acids may not be concerning, especially given her prematurity.
  3. Carnosine Levels: The elevated carnosine level is notable and may require follow-up, but it’s essential to assess it in context.

Explanation:

  • Tyrosine: An elevated level of tyrosine can be influenced by various factors, including diet and the infant's developmental stage. Since the result suggests a benign condition, it’s reassuring that the level isn’t excessively high and can resolve on its own over time.
  • Other Amino Acids (Serine, Hydroxyproline, Aspartic Acid, Hydroxylysine): Increases in these levels are often not concerning, especially for infants born slightly early. Their bodies are still adjusting, and values can fluctuate as they grow.
  • Carnosine: The elevated carnosine level of 11 is a significant finding, but rare conditions like carnosinemia require careful assessment. It’s important to discuss with your doctor for further evaluation and to rule out any issues.

Next Steps:

  1. Stay Calm and Gather Information: It’s great that you will discuss these results with your doctor soon. Prepare any questions you might have about the implications of the findings.
  2. Monitor Your Baby: Keep a close eye on your infant’s overall health, including feeding, growth, and behavior. Any significant changes should be reported to your healthcare provider.
  3. Breastfeeding Benefits: Continue breastfeeding as it provides essential nutrients and antibodies that support your newborn’s growth and immune system during this time.
  4. Limit Online Information: Try to limit exposure to overwhelming online resources, which can heighten anxiety. Focus on information from reputable sources or discussions with your healthcare professional.

It’s completely normal to feel anxious about your baby’s health. You're doing a fantastic job by seeking clarity and preparing to discuss these results with your doctor. You're not alone in this, and the medical team will provide the best guidance for your daughter's needs. Let me know if you have more questions or need further support!

Concerns About a Liver Lesion

Hello everyone, I’m reaching out for some reassurance as I await my MRI scheduled for this Friday. Currently, I’m dealing with a 6mm kidney stone that has proven difficult to pass, prompting a series of scans. My initial scan on July 5th, which was conducted without contrast, did not indicate any issues with my liver. However, during a follow-up CT on July 28th for the kidney stones, a finding was reported: a 1.9 cm hyperdense lesion located in hepatic segment 4. Given my age, the possible diagnoses discussed include focal nodular hyperplasia (FNH), hemangioma, or adenoma. It's also worth mentioning that metastasis cannot be ruled out. Therefore, the recommendations suggest a dedicated MRI of the abdomen focusing on the liver for a more thorough assessment. On the same day as the first scan, my bloodwork returned within normal ranges according to the results: albumin at 4.8, total bilirubin at 1.3, ALT at 68, AST at 44, and alkaline phosphatase at 85. Additionally, there was a note of mild hepatic steatosis in my results. At 27 years old, I have no other significant health issues aside from this. I would appreciate any insights, particularly concerning the potential for liver cancer. Thank you for any advice you can offer!

Understanding Selective IgA Deficiency: What’s Next?

Hello everyone! I recently underwent several blood tests, and I was surprised to receive the following information in the results: "Coded entry - Immunoglobulin A level (XE25B) < 0.1 g/L [0.7 - 4] - Below low reference limit. Test result - TTG ABS (IGG) Report, Normal, No Further Action Required." While I have had numerous blood tests in the past, I don’t recall experiencing a test for this specific marker before. To give you a bit of context, I have hypothyroidism, a history of recurring ear infections, and I tend to catch colds frequently (though that has improved since I began working from home a few years ago). Additionally, there have been times in the past where I've received 'false positive' results suggesting chronic infections, but follow-up tests have always reassured me that there were no underlying issues. I’m not seeking an online diagnosis, but I am genuinely intrigued about what steps might be necessary moving forward. Should I expect my doctor to contact me regarding this finding? I’ve come across information indicating that individuals with this condition may need to keep a card on hand for potential blood transfusions. I reside in the UK, which may influence how this is handled. Typically, we don’t engage directly with immunologists unless there is a serious and ongoing problem; all assessments are conducted through a general practitioner. For instance, it wasn't until I was tested for another issue that I discovered my hypothyroidism was a result of thyroiditis after several years of being unaware. Any insights or guidance would be appreciated!

Understanding Post-Sexual Bleeding

Hello everyone! Using a throwaway account for privacy reasons. At 29 years old, I received an endometriosis diagnosis six years back and have undergone three laparoscopic surgeries since, with the latest one occurring this past April. During that operation, the surgeon focused primarily on my left ovary, which had become attached to my colon due to scar tissue and was encountering blood flow problems. Additionally, they removed a section of my left fallopian tube due to necrotic tissue. Since my diagnosis, I have been using Qlaira, which has generally been effective for me. Historically, after my laparoscopies, I often experienced a cessation of periods for about 12 to 18 months. However, following my most recent procedure, I encountered a mild period the month after, no period the following month, and then a relatively heavy period two weeks ago, lasting only three days with mild cramping but no severe pain. Fast forward to this week—after having sex, not for the first time since my surgery, I have noticed symptoms resembling a menstrual flow, complete with typical blood characteristics and cramping occurring over the last three days. Before my surgery, I experienced some post-coital cramping and had a similar bleeding episode right before my operation. I would deeply appreciate any understanding or insights regarding this situation. I’m feeling quite discouraged since I just had a laparoscopic procedure, which I have previously found to provide substantial relief. Is this bleeding connected to my endometriosis or could it point to something different altogether? Was there possibly an oversight during my surgery, or could the issue have been resolved but then quickly returned? I plan to return to my gynecologist, but I need to wait another month for my insurance benefits to renew. Any advice or thoughts would be greatly appreciated in the meantime. Thanks in advance!

Concerns Regarding My Spleen Ultrasound Results

I underwent a spleen ultrasound some time ago, and during that examination, measurements were taken for the length, thickness, and width. Recently, I was asked to have another ultrasound done, but this time the measurements included height along with length and width. I noticed a major discrepancy in the height and thickness between the two sets of results, which has made me quite anxious. I'm unsure whether these terms are used interchangeably or if they represent distinct measurements. On my initial ultrasound, the thickness was recorded at 3.6, while the height from the latest scan was noted as 9.17.

Concerns About Lymphoma?

Age: 38 Gender: Female Weight: 78 kg Hello everyone. Nearly seven weeks ago, I began experiencing a dry cough accompanied by flu-like symptoms. My throat has been sore intermittently during this time. Approximately four weeks back, I discovered a lump located on the side and back of my neck. Furthermore, the lymph nodes beneath my ears and along my throat have become noticeably swollen, although there are no distinct lumps present in those areas. My doctor prescribed a course of antibiotics and steroids for a week. While the lump at the back and side of my neck has reduced in size, it remains noticeable, and there hasn't been much change regarding the swelling on the sides of my neck. My doctor ordered blood tests, but I haven’t received any feedback, so I take that as a good sign. He mentioned that it might take some time for all results to come in. I underwent an ultrasound which indicated that the lump on the back and side of my head is merely a lymph node. The medical team advised me to monitor my symptoms and return if my condition worsens or if any lumps reappear. Unfortunately, I have been experiencing significant fatigue that has escalated to a level where it hampers my daily activities. Additionally, I am suffering from abdominal pain on either side of my belly button. During the day, I frequently experience heavy sweating with physical exertion, but this does not occur at night. My temperature remains relatively stable without any significant fever. Is it feasible that having an ultrasound could be considered premature? Could there still be underlying issues?
