Yes, you could test the cord after the birth...but that's like closing the barn door after the horse gets out.
You really don't want your baby to be born with lyme disease.
If it were me, I'd go on the antibiotic that the LLMD has recommended.
From what I have read it is effective (although not 100%)
I believe it's the best chance for your newborn not to be born with lyme disease.
Here is an article that LLMD MR wrote:
"Fortunately it appears that transmission is stopped when a pregnant women with Lyme takes antibiotics. In her presentation to the International Lyme and Associated Diseases Society meeting in 2010 Sara Chissell MD notes pediatrician Charles Ray Jones MD followed 160 pregnant women with Lyme in his practice and 5% of children had laboratory evidence of Lyme transmission. Joseph Burascanno MD in his treatment guidelines reports a pregnancy registry was maintained for 11 years beginning in the late 80s by the Lyme Disease Foundation in Connecticut. It showed no transmission of Lyme when pregnant women with the illness took antibiotics during pregnancy.
Based on the above, I advise my female patients with active Lyme that pregnancy is safe with a nearly 0% risk of transmission as long as antibiotics are taken throughout the pregnancy. The oral antibiotics I suggest are amoxicillin, cefuroxime, cefdinir or azithromycin as single agents. If there is risk of bartonella transmission during the pregnancy I suggest azithromycin taken alone or in combination with one of the other three antibiotics. Doses I recommend are amoxicillin 500mg 2 pills 3 times a day, cefuroxime 500mg 1 pill 2 times a day, cefidinir 300mg 2 times a day, and azithromycin 500mg 1 time a day. In my opinion and experience these antibiotics are safe for the developing baby and the mother as well."
I have a subscript
ion, to the Treatlyme book...but I can't post the link here.
Here's what Dr. Rawls says:
"For a pregnancy complicated by Lyme disease, the mother should undergo antibiotic treatment, especially for acute Lyme disease — but always under a doctor’s supervision. Tetracyclines, including doxycycline, should be avoided during pregnancy. Herbal therapy can be a good option if antibiotics are not tolerated."/rawlsmd.com/health-articles/can-lyme-be-sexually-transmitted
I'm sure you are struggling with this....not an easy decision.
