I carried and gave birth to all three of my children, but DNA said none of them were mine. The lab hadn’t made a mistake—so whose DNA had they inherited, and how could it have come from inside my own body?

The clinic at the State University Research Hospital smelled of antiseptic and ozone. It was tucked away in the basement of a massive brick medical complex, far removed from the sterile comfort of St. Catherine’s maternity ward.

Dr. Aris Thorne was a tall man in his late fifties with untamed grey hair and sharp, analytical eyes behind rimless glasses. He didn't look at me with pity, nor did he look at me with suspicion. He looked at me like a complex mathematical equation waiting to be solved.

"Mrs. Voss," Dr. Thorne said, placing a thick stack of lab results on the desk between us. Dr. Ellison stood beside my chair, having driven down personally to oversee the examination. "I have reviewed your children's genetic profiles provided by the county laboratory. They are fascinating."

"Fascinating isn't the word I would use," I said tightly, clutching my purse against my bruised stomach. "They are taking my kids away."

"I understand the urgency," Dr. Thorne said calmly. "Look at these markers. Avery, Milo, and Mae share 100% of the exact same maternal alleles across all tested loci. That means they were unequivocally carried and conceived by the same biological mother. Yet, when we look at your cheek swab and your blood sample..." He gestured to a secondary chart. "...your blood exhibits Genomic Profile A. The children's maternal contribution exhibits Genomic Profile B."

"Profile B is my twin sister," I said.

"That is the hypothesis," Dr. Thorne replied, leaning back in his leather chair. "To prove it to a court of law, we cannot rely on theories or internet case studies. We must find physical evidence of Genomic Profile B inside your body. If you are a tetragametic chimera, your body is a mosaic. Some tissues were built from your embryonic cell line; others were built from your twin's."

"Where do we look?" Dr. Ellison asked.

"Everywhere," Dr. Thorne said plainly. "We take hair follicles from different parts of her body. We swab different mucosal membranes—oral, nasal, vaginal. And most importantly, we perform a deep cervical and endometrial tissue biopsy. If her reproductive system was formed from the second cell line, the endometrial tissue will carry Genomic Profile B—the exact profile present in her three children."

I didn't hesitate. "Do it. Do it right now."

The procedure was brutal.

Because I had given birth via C-section less than forty-eight hours prior, my body was already raw, inflamed, and tender. Dr. Ellison performed the biopsy in Dr. Thorne’s clinical examination room while Dr. Thorne carefully preserved every sample in liquid nitrogen containers, cataloging each location with rigorous legal chain-of-custody protocols.

They pulled twelve hair follicles from the nape of my neck. They took skin scrapings from my armpits, my torso, and my legs. They extracted cervical cells and endometrial scrapings.

With every painful pinch of the biopsy instruments, I closed my eyes and pictured my children.

I thought of Avery, eight years old, with her bright, inquisitive mind, sitting in her room wondering why her mother wasn't coming home. I thought of Milo, five, who couldn't sleep without me singing his bedtime song. And I thought of Mae, my tiny newborn daughter, currently feeding from a plastic bottle filled with artificial formula because the state wouldn't let her mother touch her.

"All samples are secured," Dr. Thorne announced two hours later, sealing the final biohazard vial with a tamper-evident strip. "I am running a high-density single nucleotide polymorphism (SNP) array. It will sequence the full genomic architecture of each sample."

"How long will it take?" I asked, sitting up on the examination table, dizzy from pain and blood loss.

"Normally? Three weeks," Dr. Thorne said. "But I have called the department head and declared this an emergency forensic validation. I will work through the night. We will have the preliminary genomic map by 8:00 AM tomorrow."

"The next court hearing is at 10:00 AM," Dr. Ellison warned him. "CPS is filing for permanent placement in a foster home if we cannot provide a medical explanation for the discrepancy."
